* lisp/erc/erc-backend.el (erc-server-reconnecting-p):
Don't consider erc-server-reconnecting when rendering verdict.
(erc-process-sentinel-2): ensure local variable
erc-server-reconnecting is t when timers are scheduled or running and
trying to reconnect, and nil otherwise, including after no retries
remain. Previously, its use and meaning in erc-backend were convoluted
and conflicted with its use in erc-cmd-RECONNECT (bug#50007).
* erc.el (erc-send-input-line): Previously, any line typed into a
query or channel buffer without an explicit user-command
handler (meaning most lines), would be sent twice because a trailing
newline (linefeed) would be appended. This has been verified by
checking IRCd server logs. IRCds won't return an error upon receiving
an empty message, but they also won't forward them to channel
subscribers and DM pals.
* erc-tests.el: Add test for erc-process-input-line, which also
indirectly tests erc-send-input-line. It also tests the command
lookup and dispatch facility (bug#50008).
* lisp/progmodes/cc-mode.el (c-electric-pair-inhibit-predicate):
Inhibit insertion of paired quote in fewer cases.
* test/lisp/electric-tests.el (define-electric-pair-test):
Add 'c-mode' to list of modes to test by default (bug#50538).
This ensures that quotes are paired correctly within comments, allows for
insertion of quote pairs immediately before another quote, and allows
inserting quote pairs within a string (thus splitting the string in two).
* lisp/emacs-lisp/checkdoc.el
(checkdoc-commentary-header-string): New defvar.
(checkdoc-file-comments-engine): Insert value of above new
variable instead of hardcoding what is inserted for the
"Commentary" section.
* doc/lispref/files.texi (File Attributes): Be precise when
filename does not exist in `file-has-changed-p'.
* lisp/files.el (file-has-changed-p): Suppress remote file caches.
Handle the case FILE does not exists.
In Bug#44655#32 (2020-11-19) it was reported that
rsvg_handle_get_dimensions was not deprecated. However, it became
deprecated in librsvg 2.52.0 (2021-09-15), and because of this Emacs
builds with --enable-gcc-warnings fail in Fedora 35 (2025-11-02)
with the diagnostic “‘rsvg_handle_get_dimensions’ is deprecated:
Use 'rsvg_handle_get_intrinsic_size_in_pixels' instead
[-Werror=deprecated-declarations]”.
* src/image.c (rsvg_handle_get_dimensions): Define as a DLL
function only if < librsvg 2.46.0, since it’s not used
in 2.46.0 or later.
(svg_load_image): Use rsvg_handle_get_dimensions only if librsvg <
2.46.0, since it isn’t needed if >= 2.46.0.
* lisp/emacs-lisp/pp.el (pp-max-width, pp-use-max-width): New user
options (bug#11934).
(pp-to-string): Use it.
(pp--insert-lisp): Tweak whether to use standard-output or not.
(pp--max-width): New function.
* lisp/image-dired.el (image-dired-gallery-image-root-url)
(image-dired-gallery-thumb-image-root-url)
(image-dired-gallery-dir): Don't use "path" for file names and
URLs.
* lisp/international/mule-cmds.el (confusingly-reordered): Make
sure the face looks distinct on displays that don't support the
"wavy" underline attribute.
(highlight-confusing-reorderings): Add a tooltip explaining why
the text was highlighted. Allow to remove the highlighting by
invoking the command with a prefix argument.
* lisp/progmodes/python.el
(python-shell-completion-native-get-completions): Match dummy output
even when readline is configured in non-default ways. (Bug#51010)
* lisp/vc/diff-mode.el (diff-outline-level): Make hunk headers be
at level 2.
(diff-mode): Use prettified line as outline header.
(diff--outline-level): New function (bug#51016).
* lisp/vc/vc.el (vc-diff-internal): Fix diff mode being set before
content inserted (bug#51016).
* src/nsterm.m (ns_compute_glyph_string_overhangs): When the first
glyph of a glyph string is a composite glyph, `s->nchars' is 0, so
"s->char2b + s->nchars - 1" dereferenced a position before buffer
`s->char2b'. Instead, rewrite part of the function to distinguish
between character glyphs and composite glyphs. For character glyphs,
calculate the font metrics using the `text_extents' function, passing
it the entire glyph string; for composite glyphs, call
`composition_gstring_width'. (Bug#51105)
* lisp/image-dired.el: Delete broken and commented out speedbar code;
it is not clear what, if anything, it is supposed to do. If anyone
wants to work on this, they are better off starting from scratch.
* lisp/image-dired.el: Add new section header "Gallery support" to
improve file organization. Move relevant TODO:s there.
(image-dired-gallery): New defgroup.
(image-dired-gallery-dir, image-dired-gallery-image-root-url)
(image-dired-gallery-thumb-image-root-url)
(image-dired-gallery-hidden-tags): Add options to above new defgroup.
(image-dired-add-to-file-comment-list)
(image-dired-create-gallery-lists)
(image-dired-add-to-tag-file-lists, image-dired-hidden-p): Rename to...
(image-dired--add-to-file-comment-list)
(image-dired--create-gallery-lists)
(image-dired--add-to-tag-file-lists, image-dired--hidden-p):
...this, to make it more clear that these functions are internal.
Make the old names obsolete function aliases.
(image-dired-add-to-tag-file-list): Make unused function obsolete.
* doc/emacs/misc.texi (emacsclient Options): Document the new option.
* doc/man/emacsclient.1: Mention the new option (bug#51374).
* etc/NEWS: Mention the new option.
* lib-src/emacsclient.c (reuse_frame): New variable.
(longopts): New option.
(decode_options): Decode the new option.
(print_help_and_exit): Document the new option.
(main): Use the new option.
* src/bidi.c (bidi_find_first_overridden): Extend to detect more
subtle effects of directional formatting controls, to include
embeddings and isolates.
* src/xdisp.c (Fbidi_find_overridden_directionality): Accept an
additional argument BASE-DIR to specify the base direction of the
paragraphs.
* lisp/international/mule-cmds.el (confusingly-reordered): New
face.
(reorder-starters, reorder-enders): New variables.
(highlight-confusing-reorderings): New command to detect and
highlight suspiciously reordered text.
* test/src/xdisp-tests.el
(xdisp-tests--find-directional-overrides): New test.
* etc/NEWS: Announce the new and improved features.
* etc/tutorials/TUTORIAL.he: Fix embeddings with incorrect
directions.
* doc/misc/gnus.texi (Article Display): Document it.
* lisp/gnus/gnus-art.el (gnus-treat-emojize-symbols): New user option.
(gnus-treatment-function-alist): Map.
(article-emojize-symbols): New command and keystroke.
* lisp/image-dired.el (image-dired-display-image-mode):
Inherit from 'image-mode'. (Bug#10758)
(image-dired-display-image): Don't generate a temporary image, which
is no longer needed with the above change.
(image-dired-display-thumbnail-original-image)
(image-dired-dired-display-image)
(image-dired-mouse-display-image): Simplify.
(image-dired-temp-image-file)
(image-dired-cmd-create-temp-image-program)
(image-dired-cmd-create-temp-image-options)
(image-dired-display-window-width-correction)

(image-dired-display-window-width)
(image-dired-display-window-height)

(image-dired-display-current-image-sized)
(image-dired-window-height-pixels): Make obsolete.
(image-dired-create-display-image-buffer): Make into obsolete
function alias for 'ignore'.
(image-dired-display-image-mode-map): Simplify by removing things
duplicated from `image-mode-map'. Disable some commands from
`image-mode-map' that doesn't make sense for Image-Dired.

contains anything useful.
(image-dired-minor-mode):
* doc/emacs/dired.texi (Image-Dired): Update documentation for the
above change.
