* lisp/gnus/mm-util.el (mm-mime-mule-charset-alist): For
compatibility with XEmacs, mm-mime-mule-charset-alist was first
set to a list of hard-coded entries, and then overwritten on Emacs
from `coding-system-list'. Remove the hard-coded values and
simplify the code.
Buffers `*Shell Command Output*' and `*Async Shell Command*'
have been around since a long time; used across several libraries,
they are de facto output buffers for shell commands.
* lisp/simple.el (shell-command-buffer-name)
(shell-command-buffer-name-async): New variables.
* lisp/dired-aux.el
* lisp/gnus/gnus-sum.el
* lisp/gnus/gnus-win.el
* lisp/ibuf-ext.el
* lisp/net/tramp.el: Use them.
* etc/NEWS (Changes in Emacs 28.1): Announce this change.
* doc/emacs/misc.texi (Single Shell)
* doc/misc/tramp.texi (Remote processes):
Update manual (bug#39138).
* lisp/gnus/mml.el (mml-parse-1): Use `data-encoding' to be
slightly less confusing than `content-transfer-encoding'.
* doc/misc/emacs-mime.texi (MML Definition): Document it.
* lisp/gnus/message.el (message-insert-screenshot): Adjust usage.
* lisp/gnus/message.el (message-get-reply-headers): Change how
Mail-Copies-To: never is handled (bug#37591). When that header is
present, put all the remaining recipients in the To header,
instead of picking an arbitrary recipient to have in the To
header, and the rest in the Cc header.
* doc/misc/message.texi (System Mailer Setup): Document the usage.
* lisp/gnus/gnus-art.el (gnus-url-mailto): Move most of the code
here to 'message-mailto-1' (bug#38314).
* lisp/gnus/message.el (message-parse-mailto-url): Mark as obsolete.
(message-parse-mailto-url): Rewritten slightly from the above.
(message-mailto): New command.
(message-mailto-1): New function.
* lisp/gnus/gnus-icalendar.el
(gnus-icalendar-event--build-reply-event-body): Display a warning
instead of barfing when user is missing from attendee list.
When the user identity is not present in the attendee list, an error
is triggered making replying to such an event impossible (the reply
message not being even composed). This replaces it with a warning.
This is necessary because one may receive events that the organizer
did not set up well and it is up to the user to decide whether or not
to reply to them (bug#41723).
Copyright-paperwork-exempt: yes
* lisp/gnus/message.el (message-insert-screenshot): Force scaling
to 1, since the screenshot image will already be suitable for
displaying directly (it's the same resolution).
* doc/misc/message.texi (MIME): Document it.
* lisp/gnus/message.el (message-screenshot-command): New variable.
(message-mode-map): New keystroke and menu item. Also add
mml-attach-file to the menu.
(message-insert-screenshot): New command.
* lisp/gnus/mml.el (mml-parse-1): Allow having
content-transfer-encoding already in the part, so that we can have
inline base64-encoded binaries in the Message buffers.
* lisp/gnus/mml-sec.el
(mml-secure-allow-signing-with-unknown-recipient): New variable
(bug#18393) (but this should probably be fixed in a different way).
(mml-secure-epg-sign): Use it.
(mml-secure-check-user-id): Protect against recipients that aren't
email addresses, like "No recipient".
* doc/misc/emacs-mime.texi (Display Customization): Document it.
* lisp/gnus/gnus-art.el (gnus-mime-display-single): Bind it.
* lisp/gnus/mm-view.el (mm-inline-font-lock): New variable (bug#38421).
(mm-display-inline-fontify): Use it.
* lisp/gnus/gnus-sum.el (gnus-articles-to-read): Use it.
(gnus-summary-insert-old-articles): Ditto.
* lisp/gnus/gnus.el (large-newsgroup-initial): Make the "All"
setting work by using a special symbol, instead of nil which is
indistinguishable from not being present (bug#38466).
* lisp/gnus/gnus-gravatar.el (gnus-gravatar-insert): Fix check for
repeated gravatars, which is now easier to trigger now that things
are more asynchronous.
* lisp/image/gravatar.el (gravatar--service-libravatar): Fetch the
data asynchronously (bug#40676).
(gravatar-service-alist): Adjust all providers so they are
asynchronous.
(gravatar-build-url): Adjust caller to be asynchronous.
(gravatar-retrieve): Ditto.
(gravatar-retrieve-synchronously): Ditto.
* lisp/gnus/gnus-group.el (gnus-group-new-mail): Call with Gnus
group name.
(gnus-group-catchup): Ditto.
* lisp/gnus/gnus-sum.el (gnus-summary-exit): Ditto.
* lisp/gnus/nnimap.el (nnimap-update-info): Store Gnus group name.
* lisp/gnus/nnmail.el (nnmail-check-duplication): Store unique
Gnus names in the history instead of backend-specific (possibly
duplicated) group names (bug#41842).
* lisp/gnus/gnus-start.el (gnus-active-to-gnus-format):
Add suppressive comment. Prepending "^to\\.\\|" is redundant when
'gnus-ignored-newsgroups' already matches that pattern, but adding
logic here is not worth the trouble.
* lisp/gnus/gnus-sum.el (gnus-summary-save-parts): Allow
completing over the parts in the first article in the list of the
process-marked articles (bug#39543).
* lisp/gnus/gnus-art.el (gnus-button-alist): Move the URL clauses
higher up the list before library link setup to prevent URLs ending in
".el" from failing to be recognized (and invalid library links being
created instead) (bug#39781).
* lisp/gnus/gnus-sum.el (gnus-summary-exit): Do window
configuration changes before killing off the summary buffer, so
that the window conf machinery can return to a group-only
configuration (bug#40069).
* doc/misc/gnus.texi (Article Washing): Document it.
* lisp/gnus/gnus-art.el (article-fill-long-lines): Take a numeric
prefix as the fill width (bug#38698).
* lisp/gnus/gnus-sum.el (gnus-summary-prepare-threads): Simplify both
the dummy root and the following article before comparing them,
otherwise both the former and the latter might display the thread's
subject even when gnus-summary-line-format contains "%s" (bug#40520).
* lisp/gnus/gnus-msg.el (gnus-bug): Mention the Emacs bug tracker.
* lisp/mail/emacsbug.el (report-emacs-bug): Link directly to the
Emacs portion of the bug reports (bug#41109).
* doc/lispref/processes.texi (Network): Document non-string
capability command.
* lisp/gnus/nntp.el (nntp-open-connection): Use HELP for Typhoon
and CAPABILITIES for everything else (bug#41960).
* lisp/net/network-stream.el (open-network-stream): Document
function variety of :capability-command.
(network-stream-open-starttls): Use it.
(network-stream-open-tls): Ditto.
(network-stream-open-shell): Ditto.
(network-stream--capability-command): New helper function.
* lisp/gnus/gnus.el (gnus-slave-no-server, gnus-slave): Mark as
obsolete in a way that still lets them be used as interactive
commands before Gnus is loaded.
* lisp/gnus/gnus-agent.el (gnus-slave-unplugged): Ditto (bug#42401).
