Add explicit choice for the 0 value to always show the tab bar.
Also add a choice for other non-negative numbers.
In the setter enable 'tab-bar-mode' only for numbers,
but not for the t value that should not enable the tab bar
after customization, only after creating a new tab.
By disabling hw-acceleration we can re-enable xwidgets with newer
webkit2gtk versions (Bug#80728).
Newer versions were disallowed (Bug#66068) since they abort when a
webkit view is created; however, they work fine as long as we disable
hw-acceleration, since the off-screen windows that xwidgets uses do not
support that.
* configure.ac: Remove upper-bound for webkit2gtk version check.
* src/xwidget.c (Fmake_xwidget): Turn off hardware-acceleration.

Define a short documentation group and document the major functions:
* lisp/calendar/icalendar-shortdoc.el: New file.
* lisp/calendar/diary-icalendar.el:
* lisp/calendar/icalendar-ast.el:
* lisp/calendar/icalendar-parser.el:
* lisp/calendar/icalendar-recur.el:
* lisp/calendar/icalendar-utils.el: Refer to icalendar-shortdoc.el in
file commentary.
* lisp/calendar/icalendar-macs.el: Ditto, and also mention the macros
for binding values.
* lisp/calendar/icalendar.el: Ditto, and also remove some obsolete
commentary.
Also make some improvements to documentation strings that the above
changes revealed would be helpful:
* lisp/calendar/icalendar-recur.el
(icalendar-recur-recurrences-in-window-w/end-times): Fix broken ref.
(icalendar-recur-current-tz-to-vtimezone): Clarify docstring.
* lisp/calendar/icalendar-parser.el (icalendar-parse): Clarify
docstring.
(Bug#80727)

Abstract the implementation of intervals in icalendar-recur.el. Don't
store interval NEXT-LOW when it's the same as HIGH. This reduces
allocations, and shaves about ~20% off the full test suite.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-make-interval)
(icalendar-recur-interval-low)
(icalendar-recur-interval-high)

Rearrange loops when refining subintervals, so that the loop always runs
once but doesn't run a second no-op iteration. Astonishingly this cuts
the running time of the full test suite by almost 50%.
* lisp/calendar/icalendar-recur.el (icalendar-recur-refine-byyearday)
(icalendar-recur-refine-byweekno)
(icalendar-recur-refine-bymonth)
(icalendar-recur-refine-bymonthday)
(icalendar-recur-refine-byday)
(icalendar-recur-refine-byhour)
(icalendar-recur-refine-byminute)
(icalendar-recur-refine-bysecond): Tighten up loop bounds when refining
subintervals.
Improve performance of `icalendar-recur-tz-observance-on'. This also
brings about a ~20% performance gain.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-tz-observance-on): Eliminate calculation of previous
interval recurrences when it's unnecessary. Add a cheap upper bound check to
prevent fully computing recurrences for irrelevant observances.
(icalendar-recur--w/in-locally-p):
(icalendar-recur--w/in-abs-p): New helper functions for the upper bound check.
Other more minor changes:
Improve performance in `icalendar-recur-refine-byday'
* lisp/calendar/icalendar-recur.el (icalendar-recur-refine-byday): Avoid
calculating Gregorian from absolute date unless it's necessary.
Improve performance of BYSETPOS filtering in icalendar-recur.el:
η-reduce `icalendar-recur-make-bysetpos-filter'.
Thanks to Mattias Engdegård for the suggestion and implementation.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-make-bysetpos-filter): Rename to
`icalendar-recur-bysetpos-filter' and avoid `seq-map-indexed'.
(icalendar-recur-recurrences-in-interval): Use new function.
* test/lisp/calendar/icalendar-recur-tests.el
(icalendar-test-recur-bysetpos-filter): Use new function.
Improve sorting performance:
Thanks to Mattias Engdegård for the suggestion and implementation.
* lisp/calendar/icalendar-recur.el (icalendar-recur-refine-byyearday):
(icalendar-recur-refine-byweekno):
(icalendar-recur-refine-bymonthday):
(icalendar-recur-refine-byday): Use :key instead of :lessp in `sort'
calls.
Eliminate `apply-partially' and `seq-take':
Thanks to Mattias Engdegård for the suggestion and implementation.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-recurrences-in-window): Eliminate `apply-partially'.
(icalendar-recur-recurrences-in-interval): Eliminate
`apply-partially' and replace `seq-take' with `take'.
Reduce consing:
* lisp/calendar/icalendar-recur.el
(icalendar-recur-subintervals-to-dates):
(icalendar-recur-recurrences-in-window):
(icalendar-recur-recurrences-in-window-w/end-times):
(icalendar-recur-recurrences-to-count): Replace `append' with `nconc'.
Avoid a few uses of `seq-filter' in common functions in icalendar-ast.el:
* lisp/calendar/icalendar-ast.el (icalendar-ast-node-children-of):
Reimplement filter imperatively.
* test/lisp/dired-tests.el (dired-test-ls-error-message):
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Use
`string-match-p' instead of `equal' because the error message may
report e.g. "/bin/ls" even though the value of
`insert-directory-program' is "ls".
* src/w32console.c (w32con_set_cursor_size): New function.
(w32con_reset_terminal_modes, w32con_set_terminal_modes)
(Fset_cursor_size): Use it to change cursor shape on Windows
Terminal.
* src/w32console.c (syms_of_ntterm) <w32--terminal-is-conhost>:
New variable.
(initialize_w32_display): Set 'w32--terminal-is-conhost' non-nil
when running on ConHost.
* lisp/international/characters.el (use-cjk-char-width-table):
When Emacs runs on MS-Windows Terminal, behave as if
'cjk-ambiguous-chars-are-wide' were nil even in CJK locales.
(Bug#79298)
* test/lisp/dired-tests.el (dired-test-ls-error-message):
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Make test
comparing the expected 'ls' error message with the string in the
'ls' error buffer more robust (bug#80499).
* lisp/dired.el (dired--ls-error-file): New variable.
(dired-readin-insert): Use it to find and remove entry in Dired
buffer of already deleted temporary 'ls' error file (bug#80499).
* lisp/files.el (insert-directory): Set it to temporary 'ls' error file.
* src/xdisp.c (display_line): Under WORD_WRAP, save and restore
the iterator _before_ the wrap point. This fixes face extension
under 'visual-line-mode', because otherwise 'extend_face_to_end_of_line'
is called with the value of 'it' that corresponds to the first display
element on the next screen line. (Bug#80673)
* lisp/dired.el (dired-internal-noselect): After reading in
directory, check whether there was an 'ls' error instead of
checking for file entries, since there may be none is the -Al
switches (or just -l) were used.
(dired--display-ls-error): Ensure the 'ls' error buffer is a live buffer.
* lisp/files.el (insert-directory-clean): Ensure deletion of
"//DIRED-OPTIONS//" line when using -Al switches (or just -l).
* lisp/international/textsec.el (textsec--create-script-table): Autoload
and don't define while compiling.
(uni-script): Require only when loading, not when compiling.
The previous code would sometimes exit the loop with frame1 set to the
last considered frame, even if that wasn't a suitable frame to switch
to.
* src/frame.c (delete_frame): Reset 'frame1' in the loops if we don't
match the break condition, so we don't think we've found a suitable
replacement frame if we haven't. Error if, for some reason, that
fails.
* lisp/mh-e/mh-thread.el (mh-thread-refile): Add an optional argument
'dont-update-last-destination-flag'. If it is nil, update
'mh-last-destination' and 'mh-last-destination-folder'.
Copyright-paperwork-exempt: yes
When jit-lock is not in use, `font-lock-flush` is too costly to
justify using it just to maybe update the highlighting of a few macro calls.
* lisp/progmodes/elisp-mode.el (elisp--font-lock-flush-elisp-buffers):
Skip buffers that use jit-lock, like the `*ielm*-comint-indirect` buffer.
* lisp/progmodes/elisp-mode.el (elisp--local-variables): Restore
point before calling `elisp--safe-macroexpand-all` in case this
triggers a temporary redisplay.
* lisp/subr.el (listify-key-sequence): The funny
"7th bit is Meta" applies only to unibyte strings.
* test/lisp/subr-tests.el (subr-listify-key-sequence): New test.
* lisp/vc/vc.el (with-vc-properties): Don't substitute in the
value vc-touched-properties happens to have at macro expansion
time. This was left over from when vc-touched-properties was
bound to a local gensym.
* lisp/subr.el (take-while, drop-while, all, member-if): Don't inline
if `pred` is not a "constant" since it wouldn't bring any
significant benefit. Also, don't explicitly `macroexpand-all` since
the compiler macro will be called (again) after macro-expansion,
if needed.
(internal--effect-free-fun-arg-p): Return nil for variable references.
* lisp/ffap.el (ffap-read-file-or-url): Add `read-dir` argument to
indicate we expect a directory as return value.
Avoid `read-file-name` when we want a directory and the dialog UI
might prevent us from doing so.
(dired-at-point-prompter): Use the new arg.
To break the interdependence between `cl-macs` and `cl-preloaded`,
we refrain from defining some types in `cl-macs` in some corner case
situations which affect only the early bootstrap.
`transient.el` is used during early bootstrap (while loading
`emoji.el` to produce `emoji-labels.el`) and it uses the
`keyword` and `command` types, so make sure they're not among
those types that are sometimes not defined.
Include `natnum` while we're at it, so the only types still
affected by this corner case are "Common Lisp" types, which are
less likely to be used during early bootstrap.
* lisp/emacs-lisp/cl-macs.el (natnum, keyword, command): Move type
declaration from here to...
* lisp/emacs-lisp/cl-preloaded.el (natnum, keyword, command): ...here.
* src/w32console.c (DEFAULTP, SSPRINTF, w32con_write_vt_seq)
(w32con_get_cursor_coords): New functions and macros.
(w32con_write_glyphs): Hide cursor before writing to the console.
Add code for writing in virtual-terminal mode when
'w32_use_virtual_terminal' is non-zero.

virtual-terminal mode when 'w32_use_virtual_terminal' is non-zero.
(w32con_setup_virtual_terminal): New function.
(w32con_set_terminal_modes): Call it.
(turn_on_face, turn_off_face): New functions.
(initialize_w32_display): Save background and foreground, and the
current TTY.
(Fset_screen_color): Accept an additional optional argument VTP;
if non-nil, arrange for 24-bit display to use the specified
colors.
(Fget_screen_color): Accept an additional optional argument VTP;
if non-nil, return colors used by 24-bit display.
(Fw32_use_virtual_terminal, Fw32_use_virtual_terminal_p): New
functions.
* src/term.c (tty_setup_colors) [WINDOWSNT]: Set up
virtual-terminal sequences for colors.
(init_tty) [WINDOWSNT]: Set up terminfo capabilities for Windows
virtual-terminal.
* src/xdisp.c (redisplay_internal): Don't call set_tty_color_mode
for WINDOWSNT.
* lisp/term/w32console.el (w32-tty-set-base-colors)
(w32-tty-define-base-colors, w32-tty-define-8bit-colors)
(w32-tty-define-24bit-colors, w32-tty-get-pixel): New functions.
(terminal-init-w32console): Remove color setup.
(w32-tty-setup-colors): New function.
* lisp/term/tty-colors.el (tty-color-mode-alist): Add --color
modes for 256 and 24-bit color modes.
* lisp/startup.el (tty-handle-args): Fix --color handling.
* lisp/faces.el (tty-set-up-initial-frame-faces): Set up colors
for MS-Windows consoles.
* etc/NEWS:
* doc/emacs/msdos.texi (Windows Misc):
* doc/emacs/cmdargs.texi (Colors X): Document 24-bit color support
on MS-Windows.
(Bug#79298)
* doc/misc/url.texi (Retrieving URLs): Describe the ':peer' entry
of the STATUS argument passed to CALLBACK of 'url-retrieve'.
* lisp/url/url.el (url-retrieve):
* src/gnutls.c (Fgnutls_peer_status): Doc fixes.
