Eliminate 'vtable--limit-string' in favor of the more efficient
'truncate-string-pixelwise'. Remove extraneous pre-measurement
calls to 'string-pixel-width' and ellipsis concatenation as
'truncate-string-pixelwise' does both.
The 'make-vtable' 'ellipsis' keyword can be a string to override
the default returned by 'truncate-string-ellipsis'.
* lisp/emacs-lisp/vtable.el (vtable--ellipsis): New defun.
(vtable-insert-object, vtable--insert): Use 'vtable--ellipsis'.
(vtable--insert-line, vtable--insert-header-line): Call
'truncate-string-pixelwise' instead of 'vtable--limit-string'.
(vtable--limit-string): Remove function.
* test/lisp/emacs-lisp/vtable-tests.el
(test-vtable--limit-string-with-face-remapped-buffer): Remove
test, obsoleted by misc-test-truncate-string-pixelwise.
* doc/misc/vtable.texi: Document that :ellipsis can be a string.
* lisp/files.el (find-sibling-file-search): Following expansion
of each EXPANSION, advance the search start position to reflect
the actual length of the expanded text (the updated string), not
the length of the "\\([&0-9]+\\)" (the string before expansion).

This provides limited support for window-specific overlay properties.
To complete it, we still need to add support for it to
`next/previous-single-char-property-change`.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--intangible-p):
Add `window` argument.
(cursor-sensor-tangible-pos, cursor-sensor--detect):
Pass `window` argument to the functions
looking for overlay properties.
On some profiles (after disabling syntax and refined
fontification), this was taking >90% of the time to fontify a buffer.
* lisp/vc/diff-mode.el (diff--git-preamble-overlay)
(diff--git-footer-overlay): New variables.
(diff--git-preamble-end, diff--git-footer-start): Use them to cache
the result.
* lisp/progmodes/elisp-mode.el (elisp-fontify-symbol): Mark
the 'cursor-sensor-functions' property as 'rear-nonsticky',
to adapt to 'cursor-sensor-mode' taking into account
property stickiness since f4a1c00656. See also bug#80593.
* lisp/whitespace.el (whitespace-global-mode-buffers): New custom
option.
(whitespace-enable-predicate): Use it.
(whitespace-global-modes): Refer to the new option.
This minor mode configures hs-minor-mode to use
indentation-based folding.
* lisp/progmodes/hideshow.el (hs-hideable-block-p): New
function.
(hs-indentation-respect-end-block): New option.
(hs-indentation--store-vars): New variable.
(hs-cycle-filter, hs-get-first-block-on-line, hs-get-near-block)
(hs-find-block-beg-fn--default): Adapt code to use
'hs-hideable-block-p'.
(hs-block-positions): Update.
(hs-indentation-mode): New minor mode.
* doc/emacs/programs.texi (Hideshow): Update documentation.
* etc/NEWS: Announce changes
* test/lisp/progmodes/hideshow-tests.el: Add 'require'.
(hideshow-check-indentation-folding): New test.
* lisp/simple.el (blink-matching-paren-offscreen): Inherit from
show-paren-match face.
(blink-paren-open-paren-line-string): Add blink-matching-paren-offscreen
face properties to opening paren instead of replacing original
fontification.
* lisp/paren.el (show-paren-context-when-offscreen): Mention
blink-matching-paren-highlight-offscreen in docstring.
This makes :vc behave more like 'package-vc-install'.
* lisp/use-package/use-package-core.el (use-package-normalize/:vc):
Translate :vc arguments that are just a string into a minimal
package specification containing only a :url field, thus
preventing a type error down the line.
* doc/lispref/lists.texi:
* lisp/emacs-lisp/let-alist.el (let-alist): Improve docs.
Namely, clarify that 'let-alist' does not "see" symbols
introduced by macro-expansion in its body, and that the
generated code looks up symbols in the alist whether or not
they are actually used in runtime.
See also bug#79706 for some relevant discussion.
* doc/lispref/lists.texi (Building Lists): Document it.
* etc/NEWS: Mention it.
* lisp/emacs-lisp/shortdoc.el (list): Demonstrate it.
* lisp/subr.el (ensure-proper-list): Add it.
* lisp/info.el (Info-find-node-2): Don't skip the header or
breadcrumbs line when 'scroll-conservatively' is set to a value
that could leave the beginning of the node outside of the window.
(Bug#80553)
* lisp/textmodes/flyspell.el (flyspell-generic-progmode-verify):
Take into account the word 'flyspell-auto-correct-previous-word'
moved to (i.e., the word starting at point, not the character
before point), when checking whether it should be checked/corrected
by flyspell-prog-mode. (Bug#80289)
Copyright-paperwork-exempt: yes
* lisp/vc/smerge-mode.el (smerge--refine-set-overlay-props):
New function, extracted from `smerge--refine-prepare-regions`.
(smerge--refine-prepare-regions): Take overlays rather than beg/end
arguments and remove all overlay property manipulation.
(smerge-refine-regions): Create the overlays and pass them to those
two functions.
* etc/NEWS: Describe the change.
* lisp/progmodes/etags-regen.el
(etags-regen-create-on-completion): New option.
(etags-regen-create-on-completion--set): New function.
(etags-regen-mode): Use it. Discussed in
https://lists.gnu.org/archive/html/emacs-devel/2026-03/msg00405.html
With the portable dumper it's no longer needed as discussed in
bug#79021. Originally this was done for the unexec based dumping (see
bug#4287 and commit 0e328d3779).
* lisp/progmodes/project.el: Remove stale compilation-read-command
declarations. Autoload recompile for Emacs versions prior to 31, to
allow calling project-recompile before project-compile (bug#74631).
(project-recompile): Set compilation-directory to avoid recompile
using a value unrelated to the current project (bug#68570).
An alternative to setting window-height and preserve-size is to rely
on display-buffer--maybe-at-bottom's support for
temp-buffer-resize-mode.
* lisp/progmodes/project.el (project-kill-buffers): Set
window-height to a function, not a form/cons (bug#52148).
* lisp/emacs-lisp/comp.el (comp--func-unique-in-cu-p): Check
only the callee name instead of requiring global uniqueness.
* test/src/comp-resources/comp-test-direct-call.el: New file.
* test/src/comp-resources/comp-test-direct-call-dup.el: New file.
* test/src/comp-tests.el (comp-tests-has-direct-call-p)
(comp-tests-direct-call-with-lambdas)
(comp-tests-direct-call-with-duplicate-names): New tests.
* doc/emacs/maintaining.texi (Looking Up Identifiers): Document
it.
* etc/NEWS (bindings): Mention it.
* etc/themes/newcomers-presets-theme.el (newcomers-presets): Add
it.
* lisp/progmodes/xref.el (xref-mouse-mode-map, xref-mouse-mode)
(global-xref-mouse-mode): Implement it.
* lisp/emacs-lisp/package.el (package-maintainers): Detect if
:maintainers contains on a single cons-cell, denoting a single
maintainer, in which case we wrap it in a singleton list.
With bug#59527 we ensured that the open paren line string was fontified
which was broken again with bug#63089 because there, the opening paren
was fontified with a new face.
With this change, the returned string is fontified again. Only if
`blink-matching-paren-highlight-offscreen' is non-nil, the opening paren
is unfontified and then fontified again with the
`blink-matching-paren-offscreen' face.
* lisp/simple.el (blink-paren-open-paren-line-string): Keep returned
line string fontified with slight exception if
`blink-matching-paren-highlight-offscreen' is non-nil.
* lisp/emacs-lisp/package-activate.el (package--add-info-node):
Use 'Info-default-directory-list' if Info has not been
initialized, otherwise fall back to 'Info-directory-list'
without calling 'info-initialize' beforehand, since the function
initializes 'Info-directory-list'. (Bug#80495)
* lisp/progmodes/elisp-mode.el (elisp--read-symbol-shorthands):
New function, extracted from `elisp--completion-local-symbols`.
Remember the longhand symbol in `elisp--longhand` property.
(elisp--completion-local-symbols): Use it.
(elisp--shorthand-aware-fboundp, elisp--shorthand-aware-boundp):
Use the new `elisp--longhand` property.
* etc/NEWS: Fix capitalization and markup.
* lisp/emacs-lisp/ert.el (ert--should-error-handle-error): Prefer
any over cl-some where either will do.
* lisp/epa-file.el (epa-file--find-file-not-found-function):
Reindent.
(epa-file--error-add-context): Use correct variables. Add
docstring.
* lisp/ffap.el (ffap-machine-p):
* lisp/gnus/nnmaildir.el (nnmaildir--emlink-p): Prefer
string-equal-ignore-case over case fiddling.
* lisp/gnus/gnus-search.el (gnus-search-run-query): Fix typo in
error re-signaling.
* lisp/ibuffer.el (ibuffer-confirm-operation-on): Prefer string
search over regexp matching where either will do.
* test/lisp/vc/vc-tests/vc-tests.el
(vc-test--run-maybe-unsupported-function): Pacify unused
condition-case error variable warnings (bug#72212).
