Fix intermittent rmail-summary-delete-forward problem

* lisp/mail/rmailsum.el (rmail-summary-delete-forward):
`rmail-delete-message' may apparently clear
`rmail-current-message' sometimes, so save the message number
before deleting (bug#39612).

gdb-mi: use lexical lambdas

* lisp/progmodes/gdb-mi.el (gdb-tooltip-print-1, gud-watch)
(gdb-var-list-children, gdb-edit-value)
(gdb-bind-function-to-buffer, gdb-place-breakpoints)
(gdb-preempt-existing-or-display-buffer):
Expose lambdas to the compiler as lexical closures instead of building
them the old-fashioned way.  Remove #' before lambda.

Remove unused function in gdb-mi.el

* lisp/progmodes/gdb-mi.el (gdb-var-evaluate-expression-handler):
Remove.  (It was left behind in an old code reorganisation.)

Revert "Fontify strings in {} better in tcl-mode"

This reverts commit 7f32224dc324b0ee0f1b512c8d8b19aeb80141c1.

The changes led to things like

    proc foo5 () {
        return 6
    }

being fontified as a string, which is wrong.

Small fix to the new link for inherited faces in Customize

* lisp/cus-edit.el (cus--face-link): Link to the current value of the
widget, rather than to the widget's value upon creation (bug#44154).

gdb-mi: Don't use bindat for field access

Replace uses of bindat-get-field with a simpler accessor,
since nothing here uses the bindat machinery in any way.

* lisp/progmodes/gdb-mi.el (gdb-mi--field): New.
(gdb-get-many-fields): Remove.
(gdb-var-create-handler, gdb-var-list-children-handler)
(gdb-var-update-handler, gdb-current-buffer-frame)
(gdb-update-gud-running, gdb-thread-exited, gdb-thread-selected)

(gdb-registers-handler-custom, gdb-changed-registers-handler)
(gdb-register-names-handler, gdb-frame-handler):
Use gdb-mi--field.

Temporarily mark two failing tests
; Persistently failing tests can cause problems for automated builds,
; and make it harder to spot new failures.

* test/lisp/xt-mouse-tests.el (xt-mouse-tracking-basic)
(xt-mouse-tracking-utf-8): Currently failing.

Fix history problem in `M-x shell' when started twice

variables aren't (bug#39667).  This would mean that `M-x

Escape control characters which would otherwise be blasted directly to
the terminal (when running noninteractively) with unpleasant results.

answers.

Don't rely on bignums in ntlm.el

Since ntlm.el is distributed as a separate package in GNU ELPA and
should be able to run on older Emacs versions without bignums,
we cannot make use of them here.  See discussion at
https://lists.gnu.org/archive/html/emacs-devel/2020-10/msg01665.html.
Instead, we add a small poor man's bignum implementation.

* lisp/net/ntlm.el (ntlm--bignat-of-int, ntlm--bignat-add)
(ntlm--bignat-shift-left, ntlm--bignat-mul-byte, ntlm--bignat-mul)
(ntlm--bignat-of-string, ntlm--bignat-of-digits)
(ntlm--bignat-to-int64): New.

of Lisp integers.

* lisp/abbrev.el (define-abbrevs): Make the parsing less brittle
-- allow more blank lines (bug#42611).

* lisp/net/sieve-mode.el: Use lexical-binding.

Add a link to inherited faces in Customize

* lisp/cus-edit.el (cus--face-link): New function (bug#44154).
(face): Use the function to format the link.

Don't do compilation-transform-file-match-alist if there's no file name

* lisp/progmodes/compile.el (compilation-error-properties): There
may not be a file name (bug#40111).  In that case, don't do the
`compilation-transform-file-match-alist' thing.

Don't skip empty lines when fitting mini frame to buffer (Bug#44080)

* lisp/window.el (fit-mini-frame-to-buffer,
window--resize-mini-frame, fit-frame-to-buffer,
fit-frame-to-buffer-1): By default, fit a mini frame without skipping its
buffer's leading or trailing empty lines.

Don't leak result of nested byte-compilation to outer level

* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Bind
`byte-compiler-error-flag' instead of setting it (bug#41065).
This fixes a problem of "leaking" the flag when compiling
something that then compiles something that errors out (i.e., an
"inner" compile).

Fontify strings in {} better in tcl-mode

* lisp/progmodes/tcl.el (tcl-syntax-propertize-function):
Propertize {} forms after commands as strings (bug#39277).
(tcl-set-font-lock-keywords): Fontify as strings.  This allows
things like puts {"foo} to be fontified correctly.

Copyright-paperwork-exempt: yes

`g' in *Help* doesn't require confirmation

* lisp/help-mode.el (help-mode-revert-buffer): Don't require
confirmation before reverting (bug#44202).  This mimics how most
other non-file reverting functions work.

Define backtab in text fields in eww

* lisp/net/eww.el (eww-text-map):
(eww-textarea-map): Define backtab, as in the main mode map

Add docstrings, in several cases by converting existing
comments.  (Bug#30085)
(cua--last-killed-rectangle): Update comment.

Use lexical-binding in tool-bar.el

* lisp/tool-bar.el: Use lexical-binding.

symbols as such.

most specific (bug#42966).

Fix time-test error on machines with mail

* test/lisp/time-tests.el (time-tests-display-time-update): There
may be mail on the machine (bug#44241).

Make the -modes variable autoloaded

* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):

* doc/lispref/modes.texi (Defining Minor Modes): Describe the new
:predicate keyword (bug#44232).

background colours, because that makes things harder to read.
Separate with a horizontal line instead.

font, remove from the gstring cache any lgstring that uses this
font.  (Bug#42943)

Revert "Don't consider play-sound-file to be a 'safe' function (bug#44018)"

This reverts commit cdb3c9d662c772ce25ea4d803eccd2c9e6a6ae99.

Improve documentation of display-fill-column-indicator

(display-fill-column-indicator-mode): Mention the globalized
version in the doc string.

* doc/emacs/display.texi (Displaying Boundaries): Improve and
clarify the documentation of display-fill-column-indicator.
Suggest using the minor mode as the primary means for turning the
feature on.

* src/xdisp.c (syms_of_xdisp) <display-fill-column-indicator>
<display-fill-column-indicator-character>: Doc fix.  (Bug#44226)

Don't consider play-sound-file to be a 'safe' function (bug#44018)

While there are currently no known security holes in play-sound-file,
the attack surface is considerable and historically audio file
processing has had more than its share of security problems; the
benefit to risk ratio is low.

* lisp/emacs-lisp/unsafep.el: Don't mark play-sound-file as safe.

Add section "Replacing Match" to the regexp shortdoc group

prototype.

composition_gstring_lookup_cache and return the cached composition
if it is already in the cache.

redundant (and syntactically wrong) check.

Fix problem when replacing the final char in checkdoc

Ensure that the end-of-doc-string marker is really at the end,
even if we replace the final " char in the string (bug#44201).

* INSTALL: Mention efaq.texi for installation of intlfonts.

Revert commit 1f44a776729adf9c6468a76f8310616fde62eeaa for XRef.

XRef supports Emacs versions back to Emacs 26.3, so it can’t use newer
functions such as ‘ert-resource-directory’.

* test/lisp/progmodes/xref-tests.el (xref-tests-data-dir): Don’t use
‘ert-resource-directory’

Revert commit 1f44a776729adf9c6468a76f8310616fde62eeaa for Flymake.

Flymake supports all Emacs versions back to 26.1, so it can’t use

* lisp/emacs-lisp/shortdoc.el (hash-table): New shortdoc group.

Minor doprnt cleanup: remove memchr call

* src/doprnt.c (doprnt): Remove unnecessary call to memchr.

Rename doprnt_nul to doprnt_non_null_end

* src/doprnt.c (doprnt_non_null_end): Rename from doprnt_nul,
as the old name was misleading (left over from a previous proposal).
Caller changed.

Improve doprnt performance

This patch implements some of my suggestions in Bug#8545,
with further changes suggested by Eli Zaretskii (Bug#43439).
* src/doprnt.c: Improve comments.
(SIZE_BOUND_EXTRA): Now at top level, for parse_format_integer.
(parse_format_integer): New static function, containing some of
the old doprnt.  Fix a bug that caused doprnt to infloop on
formats like "%10s" that Emacs does not use.  We could simplify
doprnt further if we dropped support for these never-used formats.
(doprnt_nul): New function.
(doprnt): Use it.  Change doprnt API to exit when either it finds NUL
or reaches the character specified by FORMAT_END.  In the typical case
where FORMAT_END is null, take just one pass over FORMAT, not two.
Assume C99 to make code clearer.  Do not use malloc or alloca to
allocate a copy of the format FMTCPY; instead, use a small fixed-size
array FMTSTAR, and use '*' in that array to represent width and
precision, passing them as separate int arguments.  Use eassume to
pacify GCC in switch statements.

Warn about a bad default value in restricted-sexp widget

* lisp/wid-edit.el (restricted-sexp widget): New :value-to-external
function.  If value is not in the internal format, then we might be
dealing with a bad default value for the widget, so display a warning
about that (bug#25152).

; Prefer https to http in more URLs

These were all tested and confirmed working.

Rework semantics of eldoc-echo-are-use-multiline-p

Rework eldoc-echo-area-prefer-doc-buffer (bug#42532)

* lisp/emacs-lisp/eldoc.el:
(eldoc-echo-area-prefer-doc-buffer): Rename from
eldoc-echo-area-prefer-doc-buffer
(eldoc-display-in-echo-area): Rework to honour
eldoc-echo-area-prefer-doc-buffer.

Introduce eldoc-display-functions

user-visible function.
(eldoc--invoke-strategy): Take INTERACTIVE arg.
Invoke eldoc-display-in-buffer
(eldoc-print-current-symbol-info): Simplify.
(Version): Bump to 1.11.0

* etc/NEWS: Mention eldoc-display-functions.

; Fix last change

Re-introduce variable for world clock timer

* lisp/time.el (world-clock--timer): New variable.
(world-clock): Save timer to above variable when it is started.
(world-clock-cancel-timer): Delete timer saved in variable instead of
searching for the function name.

This reverts commit a497b8e4a41e3223089654da4b36d0fdd51ce555.

This conversion to lexical-binding broke the eval specification,
documented in the ELisp manual.  We will probably want to add tests
for that before we can confidently convert this to lexical-binding.
Problem reported by Mattias Engdegård <mattiase@acm.org>.

Use lexical-binding in most term libraries

* lisp/term/AT386.el:
* lisp/term/internal.el:

* lisp/term/sun.el:
* lisp/term/tvi970.el:
* lisp/term/wyse50.el: Use lexical-binding.

Use lexical-binding in copyright.el and add tests

* lisp/emacs-lisp/copyright.el: Use lexical-binding.  Remove
redundant :group args.
* test/lisp/emacs-lisp/copyright-tests.el: New file.

* test/manual/image-transforms-tests.el: Use lexical-binding.

* lisp/net/tramp-sh.el (tramp-sh-handle-make-process): Accept nil
COMMAND.  (Bug#44151)

Fix a bug where the wrong menu would be triggered by mouse

For layouts such as the following, clicking the "l" in Tools with the
right window focused would trigger the File menu, not the Tools menu.
This is because the event would have window coordinate (1 . 0).
Similarly, clicking the "p" in Help would trigger the Edit menu.

Example Emacs frame:
+--------------------------------------------------------+
|File Edit Options Buffers Tools Help                    |
|;; This buffer is for text$|;; This buffer is for text $|
|;; To create a file, visit$|;; To create a file, visit $|
