* test/lisp/subr-tests.el (subr--kbd): Merge test...
(subr-test-kbd): ...with this one. Fix thinko in my previous commit.
Thanks to Mattias Engdegård <mattiase@acm.org>.
* doc/lispref/windows.texi (Buffer Display Action Functions):
Document it.
* lisp/window.el (display-buffer--action-function-custom-type): Add.
(display-buffer): Mention it.
(display-buffer-use-least-recent-window): New function (bug#45688).
* src/window.c (Fwindow_bump_use_time): New function.
* lisp/net/socks.el (socks-open-connection): Fix incomplete patch
titled "Append incremental message segments in socks-filter," which
addressed chunk ordering but neglected to zero out the work area
following successful username/password authentication (bug#45162).
* lisp/textmodes/paragraphs.el (mark-paragraph): Revert
eb090f65ce (bug#45318). This restores
the behaviour from Emacs 27 -- further work is needed on this patch.
* lisp/progmodes/project.el (project--files-in-directory):
Make sure the directory includes the trailing slash in case it's
a symlink, discussed in
https://lists.gnu.org/archive/html/emacs-devel/2021-01/msg00345.html.
* lisp/progmodes/xref.el (xref-matches-in-directory): Same.
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Same.
* lisp/emacs-lisp/eieio-core.el (eieio-defclass-autoload): Try to make
the wording of the warning about the obsoleted variable less confusing.
* lisp/emacs-lisp/bytecomp.el (byte-compile-check-variable): Don't
warn for lexical variables (Bug#39169). Fix spurious `or'.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp/warn-obsolete-variable-bound\.el): New test.
* test/lisp/emacs-lisp/bytecomp-resources/warn-obsolete-variable-bound.el:
New file.
`package-quickstart.el` files presume `package-activated-list`
is a bound variable, so make sure this is the case even when `package.el` is
not yet loaded.
It turns out there were other places that used `custom-initialize-delay`
on autoloaded variables and used various hacks to make it work with
`autoload.el`. The new code makes those hacks unneeded.
Also, there's no point trying to "optimize" those rare cases anyway,
so I simplified the `autoload.el` code for those cases.
(make-autoload): For non-trivial cases,
just include the whole `defcustom` instead of trying to mimic it.
* lisp/mail/rmail.el (rmail-spool-directory): Remove hacks.
* lisp/info.el (Info-default-directory-list): Remove `progn` hack.
* lisp/custom.el (custom-declare-variable)
(custom-handle-all-keywords): Don't use pseudo-group `nil`.
* src/nsmenu.m (ns_update_menubar): Always do a deep update for
GNUstep.
([EmacsMenu menuNeedsUpdate:]): Don't update the menu as it should
always have had a deep update.
* lisp/tab-bar.el (tab-bar--define-keys, tab-bar--load-buttons):
Move some code here from 'tab-bar-mode'.
(tab-bar-new-tab-to): Call tab-bar--load-buttons and tab-bar--define-keys.
Copyright-paperwork-exempt: yes
Speed up startup when `package-quickstart` is in use by making it possible
to load the quickstart file without having to load `package.el` at all.
(package-user-dir, package-directory-list, package-quickstart-file):
Preload those variables.
(package--get-activatable-pkg): New fun, extracted from `package-activate`.
(package-activate): Use it.
(package--activate-all): New function, extracted from
`package-activate-all`.
(package-activate-all): Use it and make the function preloaded.
(package--archives-initialize): New function.
(package-install): Use it.
(list-packages): Avoid `switch-to-buffer`.
(package-get-descriptor): New function.
* lisp/startup.el (command-line): Simplify the code now that
package-user-dir and package-directory-list are preloaded.
* lisp/emacs-lisp/autoload.el (make-autoload): Add support for
`:initialize #'custom-initialize-delay` in `defcustom`.
Be consistent when pretty-printing keys: put modifiers outside <>,
thus the more logical C-M-<return> instead of <C-M-return>.
* src/keymap.c (Fsingle_key_description):
Skip modifier prefix before adding <>.
* doc/lispref/help.texi (Describing Characters): Update example.
* doc/lispref/debugging.texi (Backtraces):
* doc/lispref/minibuf.texi (Text from Minibuffer):
Use @kbd instead of @key.
* etc/NEWS: Announce the change.
* test/src/keymap-tests.el (keymap--key-description):
* test/lisp/subr-tests.el (subr--kbd): New tests.
* lisp/progmodes/perl-mode.el
(perl-syntax-propertize-function): Handle HERE doc starter
lines ending in a comment.
(perl-heredoc): New face for HERE docs, inheriting from
font-lock-string-face.
(perl-font-lock-syntactic-face-function): Apply the new face
to HERE docs (Bug#23461).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test--run-bug-10483): Skip for Perl mode. The test
explicitly calls a function of CPerl mode.
Remove redundant `:group` args. Require cl-lib and seq.
Fix various O(n²) bug and flag a few remaining ones.
(filesets-external-viewers): Simplify regexps. Use \' instead of $.
Remove useless :constraint-flag properties.
(filesets-convert-path-list): η-reduce.

lexical variable.
(filesets-filter-list): Fix O(n²) bug.

(filesets-some, filesets-member, filesets-sublist): Make them
obsolete aliases.

(filesets-spawn-external-viewer): Use `mapconcat` to fix O(n²) bug.
(filesets-cmd-get-args): Use `mapcan` to fix O(n²) bug.
(filesets-run-cmd): Use `mapconcat` and `mapcan` to fix O(n²) bugs.
(filesets-ingroup-collect-finder): Use dynamic scoping.
(filesets-ingroup-collect-files): Use `nreverse` to fix O(n²) bug.
(filesets-ingroup-collect-build-menu): Use `mapcan` to fix O(n²) bug.
