* lisp/minibuffer.el (define-completion-category): New function.
(completion-category-get): New function, implements completion
category property lookup with (multiple) inheritance.
(completion-metadata-get, completion--styles)
(completion--cycle-threshold): Use it.
(completion-category-defaults): Mention it in docstring.
Remove entry for 'project-buffer' category, and instead...
* lisp/progmodes/project.el: ...have 'project-buffer' inherit
from 'buffer'.
* test/lisp/minibuffer-tests.el
(completion-category-inheritance): New test.
* etc/NEWS: Announce support for category inheritance.
The previous change actually introduced a bug in a closely
related but distinct place. We need to address the off-by-one
in the 'substring' call, not the 'add-face-text-property'.
* lisp/progmodes/eglot.el (eglot--sig-info): Fixup.
* lisp/isearch.el (isearch-mode): Don't override
'isearch--saved-local-map' when 'overriding-terminal-local-map'
was already set to 'isearch-mode-map' in a previous call.
(with-isearch-suspended): Don't call the function 'isearch-mode'
when the variable 'isearch-mode' is already non-nil.
* lisp/emacs-lisp/macroexp.el (macroexp--obsolete-warning): `instead`
can be a list.
* lisp/dom.el (dom-text, dom-texts): Fix obsolescence declaration.
The correct Emacs executable to use for
'elisp-flymake-byte-compile' is not necessarily the running
Emacs. For example, when editing trunk with Emacs 30,
various Lisp changes will cause spurious flymake warnings.
Add 'elisp-flymake-byte-compile-executable' to allow
customizing this.
* lisp/progmodes/elisp-mode.el
(elisp-flymake-byte-compile-executable)
(elisp-flymake-byte-compile--executable): Add. (Bug#79342)
(elisp-flymake-byte-compile): Invoke
'elisp-flymake-byte-compile--executable'.
* etc/NEWS: Announce the change.
Revert "Avoid duplicating strings in pcm--merge-completions",
commit b511c38bba. It broke
existing behavior, now covered by tests adding in this commit.
* lisp/minibuffer.el (completion-pcm--merge-completions):
* test/lisp/minibuffer-tests.el (completion-pcm-test-anydelim):
(completion-pcm-bug4219):
* lisp/vc/diff-mode.el (project-root): Declare.
(diff-find-matching-buffer): New function.
(diff-mode): Use it.
* doc/emacs/vc1-xtra.texi (Other Working Trees): Document
'C-x v w w' in diff-mode buffers.
* lisp/vc/vc-bzr.el (vc-bzr-incoming-revision):
* lisp/vc/vc-hg.el (vc-hg-incoming-revision):
* lisp/vc/vc.el (vc-diff-incoming, vc--incoming-revision): New
REFRESH optional argument.
(vc-default-log-incoming): Pass it.
* lisp/vc/vc-git.el (vc-git-incoming-revision): New REFRESH
optional argument. When nil, use cached info (bug#62940).
* lisp/tab-line.el (tab-line-define-keys): New defcustom.
(tab-line--define-keys, tab-line--undefine-keys):
New functions that explicitly bind commands from
'tab-line-mode-map' to 'ctl-x-map'.
(tab-line-mode-map): Leave this keymap empty by default
to avoid breaking 'ctl-x-map' (bug#79323).
(global-tab-line-mode): Call either 'tab-line--define-keys'
or 'tab-line--undefine-keys'.
* etc/NEWS: Announce 'let-alist' support for indexing.
* test/lisp/emacs-lisp/let-alist-tests.el (let-alist-numbers):
Add a test for 'let-alist's support for indexing.
* doc/lispref/lists.texi (Association Lists): Document indexing
with 'let-alist'. (Bug#66509)
This feature was tweaked and last tested with a 2019 edition of
the 'ccls' LSP. The spec does not clearly specify this number
to be 0-indexed, but it would make sense that it would be so.
So there's not need to 1+ - correct the numbers at all before
using them in substring. This would fix the Haskell server use
of this feature (which is bug#79259)
* lisp/progmodes/eglot.el (eglot--sig-info): Fix likely off-by-1.
