* src/process.c (glib_installs_sigchld_handler): New variable.
(init_process_emacs): Set it when GLib overrides Emacs's SIGCHLD
handler.
* src/process.h (glib_installs_sigchld_handler): Declare.
* src/xwidget.c (Fmake_xwidget): Skip the "about:blank"
workaround when glib_installs_sigchld_handler is false.
This fixes bug#81084.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1):
In the test for a cast near the end of the function, add a test
for a {...} block which isn't a statement block, allowing such
blocks to be recognized as operands of casts.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-unordered-list-marker): Skip leading
whitespace in the node range before applying the display bullet,
since the tree-sitter grammar bundles indent into the first
list_marker_* node.
* src/gtkutil.c (xg_frame_set_char_size)
(xg_frame_set_size_and_position): Round WIDTH and HEIGHT to
multiples of SCALE without adding toolbar/menubar (bug#80662).
* lisp/vc/vc.el (vc--subject-to-file-name): Make the prefix
regex less greedy, ensure the result has no text properties,
improve the docstring (bug#81017).
* lisp/erc/erc-goodies.el (keep-place-indicator): Add
`erc-keep-place-indicator-arrow' face to overlay arrow.
* lisp/erc/erc-stamp.el (erc-stamp--display-prompt-in-left-margin)
(erc--conceal-prompt): Add `erc-prompt-face' to entire `left-margin'
string. See also 9ba65aa9 "Fix missing margin face on display prop in
erc-stamp".
* test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): Update
expected text properties on prompt. (Bug#80693)
Now that markdown-ts-view-mode is demoted to "experimental" in emacs-31,
simplify bits of eglot.el and rewrite docs to be more neutral. In
practice 'gfm-view-mode' is still used if found, just like before, but
intrepid users can still try the "experimental" modes.
* lisp/progmodes/eglot.el (eglot-documentation-renderer): Rewrite
doc string.
(eglot--accepted-formats): Rewrite.
(eglot--builtin-mdown-p): Remove.
* doc/misc/eglot.texi (Customization Variables): Rewrite entry.
* etc/EGLOT-NEWS: Tweak.
The old boolean 'eglot-prefer-plaintext' is replaced by the more
expressive 'eglot-documentation-renderer', which can hold a major-mode
symbol, t (plain text), or nil (auto-detect each time). By selecting a
renderer once at startup the repeated per-request lookups are avoided,
which helps with the slowness reported in bug#81150.
* lisp/progmodes/eglot.el (eglot-prefer-plaintext): Declare obsolete
alias to 'eglot-documentation-renderer'.
(eglot-documentation-renderer): New defcustom, reworked from from
eglot-prefer-plaintext.
(eglot--accepted-formats): Use new variable.
(eglot--format-markup): Use new variable.
* etc/EGLOT-NEWS: Announce change.
* doc/misc/eglot.texi (Customization Variables): Document
eglot-documentation-renderer.
* lisp/net/eww.el (eww-form-submit): Call put-text-property to
add help-echo and shr-tab-stop properties.
(eww-tag-input): Exclude inputs with type="submit" when adding
the help-echo and shr-tab-stop properties, since that's now done
in eww-form-submit, called earlier for type="submit".
* msdos/sedlibmk.inp (GL_GNULIB_MEMEQ, GL_GNULIB_STREQ)
(GL_GNULIB_STRNUL): New substitutions, replacing that of
GL_GNULIB_STRINGEQ.
* src/term.c (init_tty) [MSDOS]: Assign appropriate value to
tty->TN_max_colors.
Do not merge to master.
* lisp/replace.el (query-replace-read-args): Add :lax-whitespace to
minibuffer-lazy-highlight-setup, so lazy highlight during
query-replace respects replace-lax-whitespace and
replace-regexp-lax-whitespace (bug#81131).

* lisp/textmodes/fill.el (fill-paragraph): Handle the case
when a non-comment line follows a comment line with
non-nil 'fill-paragraph-handle-comment' (bug#80449).
Skip such a comment line before filling a non-comment line.
* test/lisp/textmodes/fill-tests.el
(fill-test-fill-paragraph-handle-comment): Add new test.
* test/lisp/textmodes/fill-resources/fill-paragraph-handle-comment.erts:
New file.
* lisp/emacs-lisp/comp-run.el
(native--compile-skip-on-battery-p): Don't skip charging because
the battery is charging, and don't look for "discharging", at
least for now (bug#80922). Thanks to David Koppelman
<koppel@ece.lsu.edu> for the report.
* lisp/progmodes/grep.el (grep-edit-original-mode-map): New
variable.
(grep-change-to-grep-edit-mode): Save the current local map
before switching to grep-edit-mode-map.
(grep-edit-save-changes): Restore the saved local map instead of
assuming grep-mode-map (bug#81090).
