* lisp/gnus/gnus-sum.el (gnus-summary-limit-include-thread): Restore
regexp-quote that was inadvertently dropped in commit 2021-12-21 "Fix
gnus subject matching when subject is empty".
* lisp/gnus/nnselect.el (nnselect-generate-run): New function that
replaces nnselect-run.
(nnselect-store-artlist): New function.
(nnselect-get-artlist): Update function.
(nnselect-request-group, nnselect-request-thread)
(nnselect-request-create-group, nnselect-request-group-scan): Use the
new functions.
* doc/misc/gnus.texi (Selection Groups): Document artlist storage and
retrieval.
* lisp/gnus-sum.el (gnus-collect-urls-from-article): New function,
extracted from `gnus-summary-browse-url'.
(gnus-summary-browse-url): Use it; also use `browse-url-button-open-url'
to handle the prefix argument.
(gnus-summary-browse-all-urls): New command.
(gnus-summary-mode-map): Bind `gnus-summary-browse-all-urls' to "v".
* lisp/gnus/nnselect.el (nnselect-allow-ephemeral-expiry): Make
the first sentence of the doc string be a single line.
* doc/misc/gnus.texi (Creating Search Groups): Fix space between
sentences.
Articles in (persistent) groups from the gnus/nnselect backend will
now be run through the expiry process upon exit, like other persistent
groups. Expiry is not on by default for ephemeral nnselect groups but
may be turned on with nnselect-allow-ephemeral-expiry set to t.
* lisp/gnus/nnselect.el (nnselect-request-expire-articles): Make
article expiry work.
(nnselect-allow-ephemeral-expiry): New variable.
* doc/misc/gnus.texi (Creating Search Groups): Document
nnselect-allow-ephemeral-expiry.
Try to treat the file names more like file names, less like strings
to massage.
* lisp/gnus/gnus-search.el (gnus-search-indexed-parse-output): Use
`expand-file-name' to collapse separators and generally canonicalize
the name. Use `file-name-split' and joining instead of regexp
munging.
* lisp/gnus/gnus-search.el (gnus-search-make-spec): The search query
should not be interpreted as raw, but whatever the underlying search
engine expects.
* lisp/gnus/gnus-group.el (gnus-group-make-search-group):
(gnus-group-read-ephemeral-search-group): Find the real server even
when the group is native.
* lisp/gnus/gnus-search.el (gnus-search-run-search): Multiple things
wrong with collecting thread ids from the search results, and
constructing a new search query.
(gnus-search-indexed-search-command): Use list appending rather than
backtick construction, that was more confusing than it was helpful.
* lisp/gnus/gnus-search.el (*-remove-prefix): For all engine defaults,
remove incorrect docs stating this is a regexp (it's a string). Also,
use `expand-file-name' to get the correct default value, not `concat'
and (getenv "HOME").
* lisp/gnus/gnus-group.el (gnus-group-make-search-group):
(gnus-group-read-ephemeral-search-group): Ensure the server is
correctly identified even for nnselect groups.
* lisp/gnus/gnus-search.el (gnus-search-nnselect): New function.
(gnus-search-default-engines): Use it.
(gnus-search-make-spec): Queries from nnselect should always be raw.
* lisp/gnus/nnselect.el (gnus-search): Silence the byte-compiler.
* lisp/gnus/nnselect.el (nnselect-request-update-info): Use a hash and
other tricks to speed things up.
(nnselect-request-group-scan): Make sure the artlist is uncompressed.
The `format` arg has been mandatory for a while, but the backward
compatibility code that handled the case of a missing `format` arg
made it hard to notice when using the old calling convention.
* lisp/subr.el (with-demoted-errors): Warn on missing `format` arg.
* lisp/emacs-lisp/smie.el (smie-indent--separator-outdent): Don't abuse
`with-demoted-errors`.

Pass `format` arg to `with-demoted-errors`.
The `function-history` patch introduced a regression which caused
spurious compiler warnings. Fix it.
The new code also fixes a bug in the old code, thus causing some
new non-spurious warnings. Fix them as well.
* lisp/emacs-lisp/bytecomp.el (byte-compile-eval): Adjust to changes in
`load-history`.
* lisp/gnus/gnus-group.el (nnrss-discover-feed)
(nnrss-save-server-data): Use `declare-function`.

* lisp/emacs-lisp/comp.el (comp-op-case): Silence compiler warning.
bug#53352
* lisp/gnus/gnus-start.el (gnus-gnus-to-quick-newsrc-format): This
function was removing dummy.group from the global value of
`gnus-newsrc-alist' on save; we only wanted to remove it temporarily.
* lisp/gnus/gnus-registry.el (gnus-registry-enabled): Obsolete this
variable; recommend using `gnus-registry-db' as a boolean instead.
(gnus-registry-load, gnus-registry-register-message-ids,
gnus-registry-article-marks-to-chars,
gnus-registry-article-marks-to-names, gnus-registry-clear,
gnus-registry-install-p): In all these functions, test
`gnus-registry-db' instead of `gnus-registry-enabled'. We no longer
set or clear that variable.
* lisp/gnus/gnus-art.el (article--check-suspicious-addresses): Be
more resilient to junk in headers. (But all this should be rewritten
eventually, because the entire process is way too convoluted.)
* lisp/gnus/gnus-art.el (gnus-treat-suspicious-headers): New user
option.
(gnus-article-treat-suspicious-headers): New function.
(article-decode-encoded-words): Hook into the machinery to check
headers.
(article--check-suspicious-addresses): New function.
