* lisp/filesets.el:
* lisp/mh-e/mh-*.el:

* lisp/gnus/nnmaildir.el: Remove local variables that conflicts with
Emacs defaults.
* lisp/erc/erc-backend.el (erc-server-last-peers): Leave default as
nil instead of a quoted constant.
(erc-server-connect): Initialize `erc-server-last-peers' to a new
value local to a server buffer.
(erc-message): Operate on server's local `erc-server-last-peers' value
instead of the global default. Prefer replacing value instead of
mutating CDR to make for easier testing.
(erc-server-PRIVMSG): Create a new `erc-server-last-peers' for easier
testing. (Bug#56449)
* lisp/erc/erc-dcc.el (erc-dcc-chat-setup): Ensure initialization runs
in the intended buffer regardless of the value of `erc-join-buffer'.
(erc-dcc--send-final-turbo-ack, erc-dcc-get-filter): Rename internal
variable formerly known as `erc-dcc--X-send-final-turbo-ack'.
* lisp/erc/erc.el (erc-inhibit-multiline-input): Add option to cap the
number of lines to be sent before admonishing the user.
(erc-ask-about-multiline-input): Add option to ask instead of warning
user when `erc-inhibit-multiline-input' is reached.
(erc--check-prompt-input-for-excess-lines): Add validator to possibly
warn when too many lines are submitted for transmission.
* test/lisp/erc/erc-tests.el
(erc--check-prompt-input-for-excess-lines): Add test.
(Bug#54536)
* lisp/erc/erc.el (erc--pre-send-split-functions): Add new internal
hook allowing members to revise individual lines before sending. This
was created with an eye toward possibly exporting it publicly as a
customizable option.
(erc-last-input-time): Tweak meaning of variable to match likely
original intent, which is that it's only updated on successful calls
to `erc-send-current-line'.
(erc--discard-trailing-multiline-nulls): Conditionally truncate list
of lines to be sent, skipping trailing blanks. This constitutes a
behavioral change. But, considering the nature of the bug being
fixed, it is thought to be justified.
(erc--input-split): Add new internal struct containing split input
lines and flag for command detection.
(erc--input-line-delim-regexp): Add regex var for splitting multiline
prompt input.
(erc--blank-in-multiline-p): Add helper for detecting blank lines.
(erc--check-prompt-input-for-multiline-blanks,
erc--check-prompt-input-for-point-in-bounds,
erc--check-prompt-input-for-running-process): New functions to
encapsulate logic for various pre-flight idiot checks.
(erc--check-prompt-input-functions): Add new hook for validating
prompt input prior to clearing it, internal for now.
(erc-send-current-line): Pre-screen for blank lines and bail out if
necessary.
(erc-send-input): Add optional param to skip checking for blank lines.
Call hook `erc--pre-send-split-functions'.
* test/lisp/erc/erc-tests.el (erc-ring-previous-command): Use new test
helper.
(erc--input-line-delim-regexp,
erc--blank-in-multiline-input-p): Add tests.

erc-send-whitespace-lines): Add tests.
(Bug#54536)
* lisp/erc/erc.el (erc-send-input-line): Restore remedial single-space
padding to ensure empty messages typed at the prompt without an
explicit /msg aren't rejected by the server. This behavior is only
noticeable when `erc-send-whitespace-lines' is active.
* test/lisp/erc/erc-tests.el (erc-process-input-line): Add trailing
newline to more correctly simulate how it's actually called by
`erc-send-input'. (Bug#50008)
* lisp/erc/erc.el (erc-password): Deprecate variable only used by
`erc-select-read-args'. Server passwords are primarily used as
surrogates for other forms of authentication. Such use is common but
nonstandard and often discouraged in favor of the de facto standard,
SASL. Folks in the habit of invoking `erc(-tls)' interactively should
be encouraged to use auth-source instead.
(erc-select-read-args): Before this change, `erc-select-read-args'
offered to use the value of a non-nil `erc-password' as the :password
argument for `erc' and `erc-tls', referring to it as the "default"
password. And when `erc-prompt-for-password' was nil and
`erc-password' wasn't, the latter was passed along unconditionally.
This only further complicated an already confusing situation for new
users, who in most cases shouldn't be worried about sending a PASS
command at all. Until SASL arrives, they should provide server
passwords manually or learn to use auth-source.
(erc-auth-source-server-function, erc-auth-source-join-function): New
user options for retrieving a password externally, ostensibly by
calling `auth-source-search'.
(erc--auth-source-determine-params-defaults): New helper for
`erc--auth-source-search' with potential for exporting publicly in the
future. Favors :host and :port fields above others. Prioritizes
network IDs over announced servers and dialed endpoints.
(erc--auth-source-determine-params-merge): Add new function for
merging contextual and default parameters. This is another contender
for possible exporting.
(erc--auth-source-search): New function for consulting auth-source and
sorting the result as filtered and prioritized by the previously
mentioned helpers.
(erc-auth-source-search): New function to serve as default
value for auth-source query-function options.
(erc-server-join-channel): Use user option for consulting auth-source
facility. Also accept nil for first argument (instead of server).
(erc-cmd-JOIN): Use above-mentioned facilities when joining new
channel. Omit server when calling `erc-server-join-channel'. Don't
filter target buffers twice. Don't call `switch-to-buffer', which
would create phantom buffers with names like target/server that were
never used. IOW, only switch to existing target buffers.
(erc--compute-server-password): Add new helper function for
determining password.
(erc-open, erc-determine-parameters): Move password figuring from the
first to the latter.
* lisp/erc/erc-services.el
(erc-auth-source-services-function): Add new option for consulting
auth-source in a NickServ context.
(erc-nickserv-get-password): Pass network-context ID, when looking up
password in `erc-nickserv-passwords' and when formatting prompt for
user input.
(erc-nickserv-passwords): Add comment to custom option definition type
tag.
* test/lisp/erc/erc-services-tests.el: Add new test file for above
changes. For now, stash auth-source-related tests here until a
suitable home can be found.
* lisp/erc/erc-join.el (erc-autojoin--join): Don't pass session-like
entity from `erc-autojoin-channels-alist' match to
`erc-server-join-channel'. Allow that function to decide for itself
which host to look up if necessary.

(erc-autojoin--join): Add new helper containing common code from
hookees `erc-autojoin-after-ident' and `erc-autojoin-channels'.
(erc-autojoin-after-ident, erc-autojoin-channels): No longer make a
point of returning nil because the hooks they're registered on,
`erc-nickserv-identified-hook' and `erc-after-connect', don't stop on
success.
(erc-autojoin--mutate): Add helper for `erc-autojoin-add' and

instead of `erc-join'.
(erc-server-PRIVMSG): Don't call `erc-auto-query' at all, and instead
borrow the portion of its logic that detects when a query buffer
should be created instead of a channel buffer.
* lisp/erc/erc.el (erc-cmd-QUERY): Update the mode line explicitly
after calling `erc-query' in case it's needed after `erc-setup-buffer'
runs. Simplify.
(erc-query, erc--open-target): Replace uses of `erc-query'
with `erc--open-target' and make the former obsolete. Don't call
`erc-update-mode-line' because `erc-open' already does that.
(erc-auto-query): Make this function obsolete. It was previously only
used in erc-backend.el and only sewed confusion.
(erc-query-on-unjoined-chan-privmsg): Add note questioning its role.
It was previously only used by the now deprecated `erc-auto-query'.
* test/lisp/erc/erc-scenarios-misc.el
(erc-scenarios-base-mask-target-routing): Add test for server masks.
* test/lisp/erc/resources/base/mask-target-routing/foonet.eld: New file.
* lisp/erc/erc.el (erc-kill-buffer-function): Don't add hook when
loading file. Move to major-mode setup and make buffer-local instead.
Depends on tests in bug#48598.
* lisp/erc/erc-backend.el (erc-server-connected): Revise doc string.
(erc-server-reconnect, erc-server-JOIN): Reuse original ID param from
the first connection when calling `erc-open'.
(erc-server-NICK): Apply same name generation process used by
`erc-open'; except here, do so for the purpose of "re-nicking".
Update network identifier and maybe buffer names after a user's own
nick changes.
* lisp/erc/erc-networks.el (erc-networks--id, erc-networks--id-fixed,
erc-networks--id-qualifying): Define new set of structs to contain all
info relevant to specifying a unique identifier for a network context.
Add a new variable `erc-networks--id' to store a local reference to a
`erc-networks--id' object, shared among all buffers in a logical
session.
(erc-networks--id-given, erc-networks--id-create,
erc-networks--id-on-connect, erc-networks--id--equal-p,
erc-networks--id-qualifying-init-parts,
erc-networks--id-qualifying-init-symbol,
erc-networks--id-qualifying-grow-id,
erc-networks--id-qualifying-reset-id,
erc-networks--id-qualifying-prefix-length,
erc-networks--id-qualifying-update, erc-networks--id-reload,
erc-networks--id-ensure-comparable, erc-networks--id-sort-buffers):
Add new functions to support management of `erc-networks--id' struct
instances.
(erc-networks--id-sep): New variable for to help when formatting
buffer names.
(erc-obsolete-var): Define new generic context rewriter.
(erc-networks-shrink-ids-and-buffer-names,
erc-networks--refresh-buffer-names,
erc-networks--shrink-ids-and-buffer-names-any): Add functions to
reassess all network IDs and shrink them if necessary along with
affected buffer names. Also add function to rename buffers so that
their names are unique. Register these on all three of ERC's
kill-buffer hooks because an orphaned target buffer is enough to keep
its session alive.
(erc-networks-rename-surviving-target-buffer): Add new function that
renames a target buffer when it becomes the sole bearer of a name
based on a target that has become unique across all sessions and, in
most cases, all networks. IOW, remove the @NETWORK-ID suffix from the
last remaining channel or query buffer after its namesakes have all
been killed off. Register this function with ERC's target-related
kill-buffer hooks.
(erc-networks--examine-targets): Add new utility function that visits
all ERC buffers and runs callbacks when a buffer-name collision is
encountered.
(erc-networks--qualified-sep): Add constant to hold separator between
target and suffix.
(erc-networks--construct-target-buffer-name,
erc-networks--ensure-unique-target-buffer-name,
erc-networks--ensure-unique-server-buffer-name,
erc-networks--maybe-update-buffer-name): Add helpers to support
`erc-networks--reconcile-buffer-names' and friends.
(erc-networks--reconcile-buffer-names): Add new buffer-naming strategy
function and helper for `erc-generate-new-buffer-name' that only run
in target buffers.
(erc-determine-network, erc-networks--determine): Deprecate former and
partially replace with latter, which demotes RPL_ISUPPORT-derived
NETWORK name to fallback in favor of known `erc-networks-alist'
members as part of shift to network-based connection-identity policy.
Return sentinel on failure. Expect `erc-server-announced-name' to be
set, and signal when it's not.
(erc-networks--name-missing-sentinel): Value returned when new
function `erc-networks--determine' fails to find network name. The
rationale for not making this customizable is that the value signifies
the pathological case where a user of an uncommon IRC setup has not
yet set a mapping from announced- to network name. And the chances of
there being multiple unknown networks is low.
(erc-set-network-name, erc-networks--set-name): Deprecate former and
partially replace with latter. Ding with helpful message, and don't
set `erc-network' when network name is not found.
(erc-networks--ensure-announced): Add new fallback function to ensure
`erc-server-announced-name' is set. Register with post-MOTD hooks.
(erc-unset-network-name): Deprecate function unused internally.
(erc-networks--insert-transplanted-content,
erc-networks--reclaim-orphaned-target-buffers,
erc-networks--copy-over-server-buffer-contents,
erc--update-server-identity): Add helpers for
`erc-networks--rename-server-buffer'. The first re-associates all
existing target buffers that ought to be owned by the new server
process. The second grabs buffer text from an old, dead server buffer
before killing it. It then inserts that text above everything in the
current, replacement server buffer. The other two massage the IDs of
related sessions, possibly renaming them as well. They may also
uniquify the current session's network ID.
(erc-networks--init-identity): Add new function to perform one-time
session-related setup. This could be combined with
`erc-set-network-name'.
(erc-networks--rename-server-buffer): Add new function to replace
`erc-unset-network-name' as default `erc-disconnected-hook' member;
renames server buffers once network is discovered; added to/removed
from `erc-after-connect' hook on `erc-networks' minor mode.
(erc-networks--bouncer-targets): Add constant to hold target symbols
of well known bouncer-configuration bots.
(erc-networks-on-MOTD-end): Add primary network-context handler to run
on 376/422 functions, just before logical connection is officially
established.
(erc-networks-enable, erc-networks-mode): Register main network-setup
handler with 376/422 hooks.
* lisp/erc/erc.el (erc-rename-buffers): Change this option's default
to t, remove the only instance where it's actually used, and make it
an obsolete variable.
(erc-reuse-buffers): Make this an obsolete variable, but take pains to
ensure its pre-28.1 behavior is preserved. That is, undo the
regression involving unwanted automatic reassociation of channel
buffers during joins, which arrived in ERC 5.4 and effectively
inverted the meaning of this variable, when nil, for channel buffers,
all without accompanying documentation or announcement.
(erc-generate-new-buffer-name): Replace current policy of appending a
slash and the invocation host name. Favor instead temporary names for
server buffers and network-based uniquifying suffixes for channels and
query buffers. Fall back to the TCP host:port<n> convention when
necessary. Accept additional optional params after the others.
(erc-get-buffer-create): Don't generate a new name when reconnecting,
just return the same buffer. `erc-open' starts from a clean slate
anyway, so this just keeps things simple. Also add optional params.
(erc-open): Add new ID param to for a network identifier explicitly
passed to an entry-point command. This is stored in the `given' slot
of the `erc-network--id' object. Also initialize the latter in new
connections and otherwise copy it over. As part of the push to recast
erc-networks.el as an essential library, set `erc-network' explicitly,
when known, rather than via hooks.
(erc, erc-tls): Add new ID keyword parameter and pass it to
`erc-open'.
(erc-log-irc-protocol): Use `erc--network-id' instead of the function
`erc-network' to determine preferred peer name.
(erc-format-target-and/or-network): This is called frequently from
mode-line updates, so renaming buffers here is not ideal. Instead, do
so in `erc-networks--rename-server-buffer'.
(erc-kill-server-hook): Add `erc-networks-shrink-ids-and-buffer-names'
as default member.
(erc-kill-channel-hook, erc-kill-buffer-hook): Add
`erc-networks-shrink-ids-and-buffer-names' and
`erc-networks-rename-surviving-target-buffer' as default member.
* test/lisp/erc/erc-tests.el (erc-log-irc-protocol): Use network-ID
focused internal API.
* test/lisp/erc/erc-networks-tests.el: Add new file that includes
tests for the above network-ID focused functions.
See bug#48598 for background on all of the above.
* lisp/erc/erc.el (erc-default-recipients, erc-default-target):
Explain that the variable has fallen out of favor and that the
function may have been used historically by third-party code for
detecting channel subscription status, even though that's never been
the case internally since at least the adoption of version control.
Recommend newer alternatives.
(erc--current-buffer-joined-p): Add possibly temporary predicate for
detecting whether a buffer's target is a joined channel. The existing
means are inconsistent, as discussed in bug#48598. The mere fact that
they are disparate is unfriendly to new contributors. For example, in
the function `erc-autojoin-channels', the `process-status' of the
`erc-server-process' is used to detect whether a buffer needs joining.
That's fine in that specific situation, but it won't work elsewhere.
And neither will checking whether `erc-default-target' is nil, so
long as `erc-delete-default-channel' and friends remain in play.
(erc-add-default-channel, erc-delete-default-channel, erc-add-query,
erc-delete-query): Deprecate these helpers, which rely on an unused
usage variant of `erc-default-recipients'.
* lisp/erc/erc-services.el: remove stray `erc-default-recipients'
declaration.
* lisp/erc/erc-backend.el (erc-server-NICK, erc-server-JOIN,
erc-server-KICK, erc-server-PART): wrap deprecated helpers to suppress
warnings.
* lisp/erc/erc-join.el (erc-autojoin-channels): Use helper to detect
whether a buffer needs joining. Prefer this to server liveliness, as
explained above.
* lisp/erc/erc.el (erc--target, erc--target-channel,
erc--target-channel-local): Add new structs to hold info on a buffer's
target; stored in a local variable of the same name.
(erc--target-from-string): Add standalone constructor for
`erc--target'.
(erc--default-target): Add temporary internal getter to ease
transition to `erc--target' everywhere.
(erc-open): Create above items in non-server buffers.
* lisp/erc/erc-backend.el (erc-server-NICK): Recreate `erc--target'
when necessary.
* lisp/erc/erc.el (erc--valid-local-channel-p): Add internal helper to
determine whether an IRC channel is local according to its network's
CHANTYPES ISUPPORT parameter.
* test/lisp/erc/erc-tests.el (erc--valid-local-channel-p): Add test
for this helper.
* lisp/erc/erc.el (erc-login): Also known as connection passwords,
these are sent as the sole arg to the PASS command, which is nowadays
often overloaded with other semantics imposed by various entities to
convey things like bouncer or services creds.
* lisp/erc/erc.el (erc-downcase, erc--casemapping-rfc1459-strict,
erc--casemapping-rfc1459): Add new translation tables for the latter
two mappings and use them in `erc-downcase'.
* test/lisp/erc/erc-tests.el: Add test for `erc-downcase'.
* lisp/erc/erc-backend (erc--isupport-params): Add new variable to
hold a hashmap of parsed `erc-server-parameters' in a more useful
format. But keep `erc-server-parameters' around for public use. We
currently lack dedicated local variables for certain discovered IRC
session properties, such as what prefix characters are supported for
channels, etc. And the truth of this needs querying many times per
second at various points. As such, caching here seems justified but
can be easily removed if deemed otherwise because all ingredients are
internal.
(erc--parse-isupport-value): Add helper function that parses an
ISUPPORT value and returns the component parts with backslash-x hex
escapes removed. This can probably use some streamlining.
(erc--with-memoization): Add compat alias for use in internal ISUPPORT
getter. Should be moved to `erc-compat.el' when that library is fully
reincorporated.
(erc--get-isupport-entry): Add internal getter to look up ISUPPORT
items.
(erc-server-005): Treat `erc-server-response' "command args" field as
read-only. Previously, this field was set to nil after processing,
which was unhelpful to other parts of the library. Also call above
mentioned helper to parse values. And add some bookkeeping to handle
negation.
* lisp/erc/erc-capab.el (erc-capab-identify-send-messages): Use
internal ISUPPORT getter.
* lisp/erc/erc.el (erc-cmd-NICK, erc-parse-prefix,
erc-nickname-in-use): Use internal ISUPPORT getter.
* test/lisp/erc/erc-tests.el: Add tests for the above mentioned
changes in erc-backend.el.
* lisp/erc/erc.el: Require erc-networks.el, which ERC can't run
without these days. To sidestep the circular dependency, require it
last, just after erc-goodies. Remove the `declare-function' for
`erc-network-name' because it's not currently needed at load time.
(erc-log-irc-protocol, erc-hide-current-message-p): Remove `fboundp'
guard logic from `erc-network-name' invocations but preserve meaning
by interpreting `erc-network' being unset to mean module isn't loaded
or authoritative network detection has failed.
(erc-format-network): Likewise here. At the moment, this function
always returns the empty string because the function
`erc-network-name' always returns non-nil, perhaps from the
fallback/failure sentinel "Unknown", perhaps from the printed form of
nil.
* lisp/erc/erc-networks.el (erc-network): This is called throughout
erc.el but was previously cumbersome to use on account of being
guarded by `fboundp'. It now relies on the fact that its namesake
variable is set in target buffers as well.
* lisp/erc/erc.el (erc-open): whenever this function is called, the
variable `erc-server-announced-name' may be set locally in the calling
server buffer. However, if that buffer's dialed server matches that
of the one being created, the announced name is copied over on faith.
But there's no guarantee that the name will match the one ultimately
emitted by the server during its introductory burst. Beyond
potentially causing confusion in protocol logs, this behavior may
complicate debugging efforts. Setting the variable to nil helps
ensure a consistent environment when preparing a buffer for all newly
dialed connections. This commit also simplifies the setting of
`erc-server-connected', which is always nil when connecting and
vice-versa.
* lisp/erc/erc-backend (erc-server-send, erc-server-PING): Change name
of param `forcep' in `erc-server-send' to `force' and change its type
to the union of the symbol `no-penalty' and the set of all other
non-nil values. In `erc-server-PING', use this exemption when calling
`erc-server-send'. This fix was fast tracked and summarily
incorporated into bug#48598 because users of the soju bouncer are all
affected. See update #5 in the bug's email thread under the section
entitled "Riders" for an explanation.
* lisp/erc/erc-backend.el (erc--server-last-reconnect-count):
Add variable to record last reconnect tally.
* lisp/erc/erc.el (erc-reconnect-display): Add new option to specify
channel-buffer display behavior on reconnect.
(erc-setup-buffer): Use option `erc-reconnect-display' if warranted.
(erc-cmd-JOIN): Forget last reconnect count when issuing a manual
/JOIN command.
(erc-connection-established): Record reconnect count in internal var
before resetting.
(Bug#51753)
* lisp/erc/erc-backend.el (erc--unhide-prompt, erc--hide-prompt,
erc--unhide-prompt-on-self-insert): Add functions to ensure prompt is
hidden on disconnect and shown when a user types /reconnect in a
disconnected server buffer.
(erc-process-sentinel): Register aforementioned function with
`pre-command-hook' when prompt is deleted after disconnecting.
(erc-server-PRIVMSG): Ensure prompt is showing when a new message
arrives from target.
* lisp/erc/erc.el (erc-hide-prompt): Repurpose unused option by
changing meaning slightly to mean "selectively hide prompt when
disconnected." Also delete obsolete, commented-out code that at some
point used this option in its prior incarnation.
(erc-prompt-hidden): Add new option to specify look of prompt when
hidden.
(erc-unhide-query-prompt): Add option to force-reveal query prompts on
reconnect.
(erc-open): Augment earlier reconnect-detection semantics by
incorporating `erc--server-reconnecting'. In existing buffers, remove
prompt-related hooks and reveal prompt, if necessary.
(erc-cmd-RECONNECT): Allow a user to reconnect when already
connected (by first disconnecting).
(erc-connection-established): Possibly unhide query prompts.
(Bug#54826)
* test/lisp/erc/erc-tests.el (erc-tests--test-prep,
erc-tests--set-fake-server-process): Factor out some common
buffer-prep boilerplate involving user input and the server process.
Shared with bug#54536.
* lisp/erc/erc-backend.el (erc-server-reconnect): Reuse the username
argument from the previous session's USER command when reconnecting.
Also pass the existing client certificate, fixing an issue related to
bug#47788.
(erc-session-user-full-name): Move variable here from erc.el.
(erc-session-username): Add new local variable to store entry point
parameter.
* lisp/erc/erc.el (erc-session-user-full-name): Move variable to
erc-backend.
(erc-open, erc-determine-parameters, erc, erc-tls): Accept new
optional user parameter.
(erc-query): Preserve current `erc-session-username' when calling
`erc-open'.
(erc-login): Use `erc-session-username' instead of deriving it.
(erc-compute-user): Add new function to determine user name from
explicit argument or user options.
(Bug#54824)
* lisp/erc/erc-backend.el (erc-server-connect): Set
`erc-server-filter-data' to nil upon (re)connecting.
* lisp/erc/erc.el (erc-open): For the sake of clarity, don't
initialize `erc-server-filter-data' here because non-connect
invocations merely set up a target buffer and have no business
touching this variable.
* lisp/erc/erc.el: Declare needed variables exported by erc-backend.el
as special near the top of the file, and only require `erc-backend'
after providing `erc' as a feature at the very end.
* lisp/erc/erc-backend.el: Don't preemptively provide `erc-backend'.
* test/lisp/erc/erc-tests.el (erc--meta--backend-dependencies): Add
utility test to scrape for unused vars that may accumulate over time.
(Bug#54825)
* lisp/erc/erc-backend.el (define-erc-response-handler): Use
`format' here instead of `format-message' since Emacs will expand
the doc string later when the user asks for help about the symbols
defined.
* lips/erc/erc-dcc.el (erc-dcc-open-network-stream): Use TLS
for new connections when :secure flag is set.
(erc-dcc-do-GET-command): Set secure flag when user explicitly passes
an "-s" option.
(erc-dcc-do-LIST-command): Show an "s" to indicate a secure connection
when applicable.
(erc-dcc-query-handler-alist): Add extra items for "SSEND", etc.
(erc-dcc-handle-ctcp-send): Set secure flag when a leading "S" appears
in the command type.
* lisp/erc/erc-dcc.el (erc-dcc-list): Document optional :turbo item.
(erc-message-english-dcc-list-{head,line,item}): Adjust format strings
to make room for "(T)" turbo indicator.
(erc-dcc-do-GET-command): Optionally set :turbo in `erc-dcc-list'
entry when passed "-t" in the "/DCC GET" slash command. Also add
switch to command line in front-matter Commentary, but refrain from
publicizing further because our implementation is only defensive and
only for receiving.
(erc-dcc-do-LIST): Print message with new format specifier for turbo
status.
(erc-dcc-ctcp-query-send-regexp): Account for T- and S-prefixed
commands. Receiving from an SSEND-capable sender will be added in a
subsequent commit.
(erc-dcc-handle-ctcp-send): Set :turbo item in `erc-dcc-list' member
when new match group is nonempty.
(erc-dcc--X-send-final-turbo-ack): New internal variable and potential
future option for extreme corner cases involving maverick turbo
senders, like WeeChat, who don't use the TSEND command variant.
(erc-dcc-get-filter): Don't send when turbo is active.
* test/lisp/erc/erc-dcc-tests.el: Add new file.
(Bug#54458)
* lisp/erc/erc-dcc.el (erc-dcc-member): Be more tolerant in the
catch-all case by testing for equality instead of identity.
(erc-dcc-do-GET-command): Pass file name when querying
`erc-dcc-member'. (Bug#54458)
* lisp/erc/erc-dcc.el (erc-dcc-get-sentinel): Display error when total
byte count received is lower than expected.
(erc-message-english-dcc-get-failed): Add `dcc-get-failed' to the
English messages catalog.
(erc-dcc-get-file): Tweak initialization of `erc-dcc-entry-data'.

Oriya to Odia. Improve Oriya composition rules.
* lisp/leim/quail/indian.el ("odia"): New input method.
* lisp/erc/erc-lang.el: Obsolete the iso-638-languages variable
(which was a typo) and replace it with iso-639-1-languages.
