* 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.
Reported and reduced by Mauricio Collares.
* lisp/emacs-lisp/comp.el (comp-final): Fix coding system for the
tmp file used to pass data the child processes.
* test/src/comp-tests.el (45603-1): New testcase
* test/src/comp-test-45603.el : New File.
* 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.

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.
(filesets-eviewer-constraint-p): Mark :constraint-flag as obsolete.
(filesets-spawn-external-viewer): Can't use `run-hooks` on
lexical variable.
(filesets-filter-list): Fix O(n²) bug.
(filesets-ormap): Simplify.
(filesets-some, filesets-member, filesets-sublist): Make them
obsolete aliases.
(filesets-reset-fileset): Simplify.
(filesets-directory-files): Use `push`.
(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.
Without this fix, the build on AIX 7.2 with xlc fails in the ‘CCLD
temacs’ step with the diagnostic ‘ld: 0711-317 ERROR: Undefined
symbol: BC’. This is because -lcurses does not define BC etc.
* configure.ac: When building terminfo.o, define
TERMINFO_DEFINES_BC if the library defines BC etc.
* src/terminfo.c (UP, BC, PC): Define depending on
TERMINFO_DEFINES_BC, not on TERMINFO.
(cherry picked from commit 632917461a)
* lisp/net/tramp-sh.el (tramp-sh-handle-insert-directory): Let buffer be
unibyte when applying numbers returned with the ls --dired option.
Reported by Justus Piater <Justus-dev@Piater.name>.
* test/lisp/net/tramp-tests.el (tramp--test-check-files): Extend test.
* doc/misc/widget.texi (Basic Types): The user options
widget-glyph-directory and widget-glyph-enable were renamed long ago
to widget-image-directory and widget-image-enable, but the manual
kept calling them by their old names. Update the names.
