* doc/misc/widget.texi (Widgets and the Buffer): Fix the
signatures of 'widget-forward' and 'widget-backward'. Reported by
Tim Landscheidt <tim@tim-landscheidt.de>.
* lisp/wid-edit.el (widget-forward, widget-backward)
(widget-move): Doc fixes.
* lisp/progmodes/etags.el (etags--xref-backend):
Move the definition to autoloads, so that etags.el doesn't have to
be loaded before it really is used.
* doc/emacs/maintaining.texi (Looking Up Identifiers):
Mention that 'M-.' can signal an error.
(Xref): Recommend using 'etags-regen-mode' (bug#43086).
* etc/NEWS: Add updated marks.
* lisp/vc/vc-dispatcher.el (vc-user-edit-command-history): Use
this as a dynamically bound variable, not a minibuffer history.
(vc-user-edit-command): Pass its value to read-shell-command.
* lisp/vc/vc-git.el (vc-git--pushpull):
* lisp/vc/vc.el (vc-edit-next-command): Bind it.
(vc-edit-next-command-history): New variable.
* etc/NEWS: Document the change.
* lisp/progmodes/xref.el (xref-find-backend):
Allow returning nil (bug#43086).
(xref-backend-definitions, xref-backend-apropos):
Signal user-error when no backend is available. The error text
suggests a few built-in Xref backends.
(xref-backend-identifier-completion-table): Default to nil.
(xref--no-backend-available): New helper function.
* lisp/progmodes/etags.el (etags--xref-backend):
Return nil when no tags table is visited.
Just because a specific request of a specific "hint" is
cancelled doesn't mean we can cancel the other's too. Also
eglot-advertise-cancellation = nil was subtly broken.
This manifested itself mostly in Eglot semantic tokens.
* lisp/progmodes/eglot.el (eglot--async-request): Fix thinkos.
* lisp/align.el (align-region): Use markers to ensure the regions
stay accurate after overlapping aligning modifications. (Bug#80316)
* test/lisp/align-tests.el (align-c-multi-section): New test.
It is both simpler to code and marginally more general (allows
spaces in arguments).
* lisp/textmodes/yaml-ts-mode.el (yaml-ts-mode-yamllint-options): Use
a list.
(yaml-ts-mode-flymake): Adjust accordingly.
* test/lisp/vc/vc-git-tests.el (vc-git-test-branch-remotes):
The 'unset' subcommand to 'git config' was introduced in git 2.46; use
the '--unset' option instead.
* src/xdisp.c (move_it_vertically_backward): Zero out cached value
of line height, to avoid using stale and incorrect values.
(try_window_reusing_current_matrix): Fix conditions for changes in
tab-line height.

This improves the scrolling a little bit, but doesn't solve the
problem entirely.
* lisp/progmodes/elisp-mode.el (elisp-byte-code-syntax-propertize):
Reset point to just after the start of the previous match so that we
don't skip past the end of the lazy string, which can happen if it's
zero-length; that could lead to an infinite loop.
macOS 26 introduced new event processing behavior that causes scrolling
lag and input handling problems in Emacs. This patch disables two
features via NSUserDefaults when built against the macOS 26 SDK:
- NSEventConcurrentProcessingEnabled
- NSApplicationUpdateCycleEnabled
This fix is based on the equivalent patch in emacs-mac by Mitsuharu
Yamamoto. See: https://bitbucket.org/mituharu/emacs-mac/commits/e52ebfd
* src/nsterm.m (ns_term_init): Disable problematic event processing
when built for macOS 26+. (Bug#80268)
This option controls the format of the help-echo when hovering
over the time display in mode line. (Bug#80143)
* lisp/time.el (display-time-help-echo-format): Add option.
(display-time-string-forms): Use it.
* etc/NEWS (Time): Announce the new option.
