* lisp/vc/ediff-vers.el (ediff-vc-revision-other-window)
(ediff-vc-working-revision): Redefine Emacs 22 compatibility
aliases as obsolete function aliases.
(ediff-vc-internal, ediff-vc-merge-internal): Don't use the now
obsolete aliases.
* lisp/cedet/semantic/wisent/comp.el (wisent-ISVALID-TOKEN)
(wisent-parse-nonterminals):
* lisp/cedet/semantic/wisent/wisent.el
(wisent-item-to-string): Remove XEmacs compatibility code.
(wisent-char-p): Redefine as obsolete function alias for
'characterp'.
* lisp/progmodes/cc-engine.el (c-end-of-macro): Fix faulty cache handling,
where the upper bound of c-macro-cache was never being set.
(c-forward-comment-minus-1): New macro which terminates unwanted indefinite
backward searching with lots of escaped newlines in c-backward-single-comment.

overflow while handling the large C Macro.
Emacs 23.2 was released 10 years ago. old-whitespace.el has a
replacement in whitespace.el and is no longer relevant. The other
libraries implement compatibility with Lucid Emacs, a modified version
of Emacs last released in the 1990s.
* lisp/obsolete/ledit.el:
* lisp/obsolete/lmenu.el:
* lisp/obsolete/lucid.el:
* lisp/obsolete/old-whitespace.el: Delete files. These libraries have
been obsolete since Emacs 23.1 or 23.2.
* etc/NEWS: Announce their deletion.
* admin/authors.el (authors-ignored-files)
(authors-fixed-entries, authors-valid-file-names):
* lisp/emulation/viper.el (viper-mode):
* lisp/ffap.el (ffap-menu-ask): Remove references to deleted files.
Hopefully this aids in getting the package correctly listed in GNU
ELPA.
* lisp/progmodes/xref.el (Version): Bump to 1.0.1
(Package-Requires): Require project 0.1.1.
Add a new function, file-modes-number-to-symbolic.
Make archive-int-to-mode and obsolete alias of it; use it
to define tar-grind-file-mode (Bug#27952).
* lisp/files.el (file-modes-number-to-symbolic): New defun.
* lisp/arc-mode.el (archive-int-to-mode): Make it an obsolete alias.
* lisp/tar-mode.el (tar-grind-file-mode):
Use file-modes-number-to-symbolic.
* test/lisp/arc-mode-tests.el (arc-mode-test-archive-int-to-mode)
* test/lisp/tar-mode-tests.el (tar-mode-test-tar-grind-file-mode):
Update test.
* test/lisp/files-tests.el (files-tests-file-modes-symbolic-to-number)
(files-tests-file-modes-number-to-symbolic): New tests.
* doc/lispref/files.texi (Changing Files): Document the new funtion.
* etc/NEWS (Lisp Changes in Emacs 28.1): Announce it.
Computing determinant and inverse for on some matrices containing
non-numeric elements failed or gave the wrong result.
Reported by Mauro Aranda.
* lisp/calc/calc-mtx.el (math-do-matrix-lud): Don't use zero as pivot.
* test/lisp/calc/calc-tests.el (calc-matrix-determinant): New test.
* lisp/calendar/cal-julian.el (diary-julian-date)
(diary-astro-day-number): Silence byte-compiler warning about variable
'declared after its first use'.
The new packages state they require Emacs 26.3 to function, but a
small part of project.el breaks this "soft" rule: the two functions
requiring fileloop.el are incompatible with Emacs 26.3.
* lisp/jsonrpc.el: Tweak comment near Package-Requires.
* lisp/emacs-lisp/eldoc.el: Add Version and Package-Requires.
* lisp/progmodes/flymake.el: Add comment near Package-Requires.
* lisp/progmodes/project.el: Add Version and Package-Requires.
* lisp/progmodes/xref.el: Add Version and Package-Requires.
* lisp/calendar/cal-bahai.el (calendar-bahai-month-name-array):
There doesn’t seem to be any disagreement in the sources I
consulted that “Mas͟híyyat” and “S͟haraf” both need an “s͟h” digraph
instead of plain “sh”.
Allow use of `syntax-ppss-flush-cache` in `syntax-propertize-function`.
(syntax-propertize--inhibit-flush): New var.
(syntax-propertize): Bind it.
(syntax-ppss-flush-cache): Test it.
* lisp/emacs-lisp/timer-list.el (timer-list-mode)

(timer-list--function-predicate): Add support for sorting by column.
* lisp/emacs-lisp/timer-list.el (list-timers)
(timer-list-mode): Inherit from 'tabulated-list-mode' instead of
'special-mode' and make the necessary changes to support that.
* doc/lispref/os.texi (Timers): Update documentation.
Pacify GCC 10.1.0 so that it does not issue false alarms
when Emacs is configured with --enable-gcc-warnings.
* src/dispnew.c (clear_glyph_row):
* src/fns.c (hash_clear):
* src/keyboard.c (append_tab_bar_item):
* src/lisp.h (vcopy):
* src/xfaces.c (get_lface_attributes_no_remap)
(Finternal_copy_lisp_face, realize_default_face):
* src/xmenu.c (set_frame_menubar):
Work around -Warray-bounds false alarm in GCC 10.1.0.
* src/intervals.c (copy_properties):
Avoid -Wnull-dereference false alarm in GCC 10.1.0.
* src/lisp.h (xvector_contents_addr, xvector_contents):
New functions, useful for working around GCC bug 95072.
Strategy: when an instrumented function gets re-evaluated, save the former
value of its symbol's `edebug' property in the new propery `ghost-edebug'. If
this function is still being edebugged, edebug will then access its info from
this new property.
Also fix the bug whereby compile-defun'ing an instrumented function prevents
the function being re-instrumented by I (edebug-instrument-callee).
* lisp/emacs-lisp/edebug.el (edebug-get-edebug-or-ghost): New function.
(edebug-read-and-maybe-wrap-form1): save value of `edebug' property in
'ghost-edebug'.
(edebug-make-form-wrapper): Set value of `ghost-edebug' to nil.
(edebug-make-form-wrapper, edebug-find-stop-point, edebug-next-break-point)
(edebug-modify-breakpoint, edebug--overlay-breakpoints, edebug-set-breakpoint)
(edebug-unset-breakpoints, edebug-toggle-disable-breakpoint)
(edebug--backtrace-goto-source, edebug-display-freq-count)
(edebug-set-conditional-breakpoint): Use edebug-get-edebug-or-ghost to access
edebug information.
(edebug-instrument-function): Also check a function is a cons before declaring
it "already instrumented".
In the top-level construction of the entry-type commands,
use `defalias` instead of (eval `(defun ...)).
(bibtex-insert-kill): Strength reduce `eval` => `symbol-value`.
(bibtex-autokey-before-presentation-function): Avoid nil value.
* lisp/gnus/message.el (message-tool-bar-retro):
Use non-Gnus-specific icon.
* lisp/term/x-win.el (x-gtk-stock-map):
Use more themed icons (bug#40990).
(pcase--fgrep): Change calling convention to take bindings rather than
just variables.
(pcase--funcall, pcase--eval): Adjust to this new calling convention.
(pcase--expand): Use `pcase--fgrep` to bind only the vars that are used.
