* lisp/emacs-lisp/edebug.el (edebug-prepare-margin): New
function to set up left margin for Edebug.
(edebug--display-1): Use it.

Make 'outline-search-function' a user option with named choices for
its predefined values, so users can configure it via Customize.
Preserves existing docstring and runtime semantics (bug#81053).
* lisp/outline.el (outline-search-function): Convert to defcustom.
* etc/NEWS: Announce it.
Add outline-search-from-regexp generic helper (bug#80887)
Minor modes and third-party packages that customize 'outline-regexp'
typically need an 'outline-search-function' implementation that
searches for 'outline-regexp' anchored at beginning of line. Without
a generic helper, each such user reinvents the function locally.
Add it to outline.el.
This pattern has been in production use as a default value of
'outline-search-function' (set via 'setq-default') without issues.
* lisp/outline.el (outline-search-from-regexp): New function.
* etc/NEWS: Announce it.
This change helps ensure that work buffers are "clean" for reuse
by arbitrary callers.
* lisp/emacs-lisp/subr-x.el (work-buffer--release): Call
'kill-all-local-variables' with KILL-PERMANENT 'reset.
* src/buffer.c (Fkill_all_local_variables): If KILL-PERMANENT is
'permanent-local, kill all locals without prejudice. If
KILL-PERMANENT is 'reset, also call 'reset_buffer'.
* test/lisp/emacs-lisp/subr-x-tests.el
(subr-x-with-work-buffer-locals-killed): New test.
* doc/lispref/variables.texi: Update 'kill-all-local-variables'
documentation.

This ensures defcustom ':set' functions are invoked. The new
user option 'setopt-local-type-mismatch' can prompt users to
accept or discard type-mismatched values or to always accept or
discard such values.
* lisp/cus-edit.el (setopt-local-type-mismatch): New defcustom.
(setopt--set-local): Consult setopt-local-type-mismatch.

(outline-mode-menu-bar-map): Use 'outline-show-entry-and-parents'
instead of 'outline-show-entry'.
(outline-isearch-open-invisible): Use the new command instead of
the 'outline-show-entry' primitive. This prevents unintended
side effects for packages relying on the base API and avoids the
'isolated item' effect.
(outline-show-entry-and-parents): New function to climb the tree,
reveal parent headings, and unfold the current entry (bug#79286).
* lisp/vc/vc-dir.el (vc-dir-show-outgoing-count): Mark obsolete.

motion on text terminals.

(dbus-check-event, dbus-handle-event): HANDLER can also be
(HANDLER . ERROR-HANDLER).

This ensures that if the child process closed its stdin and Emacs tries
to write to it, the process can still do any remaining work and exit
normally. In practice, this can occur with commands like "head(1)"
(bug#79079).
* src/fileio.c (file_for_stream): New function, extracted from...
(Fset_binary_mode): ... here.
(Ffile__close_stream): New function.
* src/process.c (send_process): When encountering EPIPE, only close the
fd for the pipe to the child process's stdin.

for process liveness anymore.
* test/src/process-tests.el (process-tests/broken-pipe): New function.
(process-tests/broken-pipe/pipe, process-tests/broken-pipe/pty)
(process-tests/broken-pipe/pipe-stdin)
(process-tests/broken-pipe/pty-stdin): New tests.

* lisp/emacs-lisp/package-vc.el (package-vc--clone): Implement
logic to find and copy files from a previous installation.
(package-vc-install): Indicate the effect of the prefix argument
in the prompt.
Allow completion "frontends" to provide extra information
that the backends they call can use to adjust or optimize
their behavior.

https://yhetil.org/emacs/jwv7bpl28y6.fsf-monnier+emacs@gnu.org/
* lisp/minibuffer.el (completion-frontend-properties):
New variable.
(completion-lazy-hilit-p): New function.
(completion-hilit-commonality, completion-lazy-hilit)
(completion-pcm--hilit-commonality)
(completion-flex-all-completions): Use it instead of
checking the 'completion-lazy-hilit' variable directly.

* etc/NEWS: Announce 'completion-frontend-properties'.
A new basic face 'margin' is used for text displayed in the left and
right margin areas, i.e., the areas typically used by VCS and LSP
packages for per-line annotations. Its background defaults to the
frame default, preserving existing behavior for users who do not
customize it.
* etc/NEWS: Document the new 'margin' face.
* lisp/faces.el (margin): Add 'margin' face, inheriting from 'default'.
* src/dispextern.h (face_id): Add MARGIN_FACE_ID.
* src/xdisp.c (face_at_pos): Use 'margin' as the base face for
strings displayed in margin areas so that they inherit the gutter
background by default.
(extend_face_to_end_of_line): Compute 'margin_fill_face_id' from the
'margin' face. Use while loops to explicitly fill all empty character
slots in both left and right margins for both GUI and TTY branches.
(display_line): Call 'extend_face_to_end_of_line' for beyond-EOB rows
when the window has margins. Also extend the existing condition for
text rows with empty margins to trigger when the 'margin' face
background differs from the frame default, not only when the default
face is remapped.
* src/xfaces.c (realize_basic_faces): Realize 'margin' as a basic
face to support face-remapping and efficient lookup.
(Bug#80693)
In terminal sessions, SIGINT is turned into a `quit` ELisp signal,
but in batch it has traditionally killed Emacs. It can be very
useful to cause a `quit` from outside the process when running
in batch (e.g. for "batch" sessions that provide a REPL via stdin/out),
so add a new var 'kill-emacs-on-sigint' to control that behavior.
(bug#80942)
* src/keyboard.c (handle_interrupt_signal): Obey `kill_emacs_on_sigint`.
(init_keyboard): Use `deliver_interrupt_signal` for SIGINT also for
batch sessions.

`kill-emacs-on-sigint` in batch mode.

the CAPF.

This enables features unrelated to native image APIs, such as
'w32-export-frame' and 'yank-media', which need to call GDI+
functions.
* configure.ac (HAVE_W32) [!CYGWIN]: Always include w32image.o in
W32_OBJ.
* etc/NEWS: Drop 'yank-media' '--without-native-image-api' caveat.
