* lisp/vc/diff-mode.el (diff--font-lock-prettify):
Use 'window-fringes' instead of the 'left-fringe' frame parameter
since the former returns an integer on both GUI and TTY frames.
* lisp/vc/vc-git.el (vc-git-modify-change-comment): Bind
coding-system-for-write to locale-coding-system around the call
to vc-git-command on MS-Windows. The temporary file name could
contain non-ASCII, e.g. the user's username.
* lisp/vc/vc.el (vc-buffer-sync-fileset): Check whether a
buffer's file is in one of our directories before checking
whether it exists on disk. This should mean far fewer system
calls overall (bug#79137).
* lisp/vc/vc-hg.el (vc-hg-checkin-patch): Use
make-nearby-temp-file. Protect the async process with
vc-wait-for-process-before-save. Don't call vc-checkin-hook
here, instead return a (async . #<process>) list so that
vc-finish-logentry does it.
* lisp/vc/vc-git.el (vc-git-delete-working-tree): Reimplement to
avoid requiring 'git worktree remove'.
(vc-git-move-working-tree): Use 'git worktree move' if 'git
worktree repair' is not available. Give a more informative
error message if we don't even have that.
* test/lisp/vc/vc-tests/vc-tests.el (vc-git--program-version):
Declare.
(vc-test--other-working-trees): Skip vc-move-working-tree tests
with Git old enough to lack 'git worktree move'.
* lisp/vc/vc.el (vc-working-tree-switch-project): New command.
* lisp/vc/vc-hooks.el (vc-prefix-map): Bind it to C-x v w s.
* doc/emacs/vc1-xtra.texi (Other Working Trees):
* etc/NEWS: Document it.
* lisp/vc/vc.el (vc-move-working-tree): Check entries in
vc-dir-buffers for liveness. Don't hardcode "*vc-dir*"; instead
call uniquify-buffer-base-name. Call uniquify-rename-buffer,
not rename-buffer, so that the buffer is not marked unmanaged.
* lisp/vc/vc.el (vc-add-working-tree, vc-move-working-tree):
Have project-remember-project move the new working trees to the
front of the list of projects. Suggested by Dmitry Gutov
<dmitry@gutov.dev>.
* lisp/progmodes/project.el (project--remember-dir)
(project-remember-project): New STABLE argument.
* lisp/vc/vc.el (vc-add-working-tree)
(vc--prompt-other-working-tree, vc-move-working-tree): Use it.
* lisp/progmodes/project.el
(project-find-matching-buffer-function): New variable.
(project-find-matching-file): Delete.
(dired-current-directory): Declare.
(project-find-matching-file-or-directory): New function. Like
the old 'project-find-matching-file', but also handle Dired
buffers (bug#79126). When matching file/directory does not
exist, try going up in the directory tree until we find
something that does.
(project-find-matching-buffer): New command.
* lisp/vc/vc.el (vc-switch-working-tree): Use it (bug#79126).
* etc/NEWS: Announce new command and new variable.
* lisp/vc/vc-annotate.el (vc-annotate--file-name-change):
New function (bug#26345).
(vc-annotate-warp-revision): Use it here.

* lisp/progmodes/project.el (project-prompter)
(project-prompt-project-dir, project-prompt-project-name): New
PREDICATE and REQUIRE-KNOWN optional arguments.
* lisp/vc/vc.el (project-prompter): Declare.
(vc--prompt-other-working-tree): New function.
(vc-switch-working-tree, vc-delete-working-tree)
(vc-move-working-tree): Use it to prompt for the other working
tree in a way that respects 'project-prompter' (bug#79024).
* etc/NEWS: Announce all three optional arguments. Rework
description of new optional argument to 'project-current'.
* lisp/vc/vc-git.el (vc-git-known-other-working-trees):
* test/lisp/vc/vc-tests/vc-tests.el (vc-test--other-working-trees):
Tolerate directories with symlinks in them, such as the standard
temporary dirs on MacOS. 'git worktree list' outputs expanded names.
* lisp/vc/vc-dispatcher.el (vc-do-command): Don't append " ." to
'full-command' when FILES is nil because the command we actually
run doesn't have "." as a final argument in that case.
* lisp/vc/vc-git.el (vc-git--read-start-point): New function,
factored out of vc-git-create-tag.
(vc-git-create-tag): Use it.
(vc-git--worktrees, vc-git-known-other-working-trees)
(vc-git-add-working-tree, vc-git-delete-working-tree)
(vc-git-move-working-tree):
* lisp/vc/vc-hg.el (vc-hg-known-other-working-trees)
(vc-hg-add-working-tree, vc-hg--shared-p)
(vc-hg-delete-working-tree, vc-hg-move-working-tree): New
functions.
* lisp/vc/vc.el: Define API for known-other-working-tree,
add-working-tree, delete-working-tree and move-working-tree
backend functions.
(vc-dir-status-files): New function.
(project-current-directory-override): Declare.
(dired-rename-subdir): Autoload.
(vc-add-working-tree, vc-switch-working-tree)
(vc-delete-working-tree, vc-move-working-tree): New commands.
* lisp/vc/vc-hooks.el (vc-prefix-map): Bind them under C-x v.

(vc-test--other-working-trees): New function.
(vc-test-git07-other-working-trees)
(vc-test-hg07-other-working-trees): New tests.
* lisp/ldefs-boot.el: Regenerate.

* etc/NEWS (bindings): Document the new binding.
* lisp/vc/diff-mode.el (diff-read-only-map): New keymap,
factored out of code modifying minor-mode-map-alist.
(diff-mode): Include bindings from diff-read-only-map in
docstring (bug#34080).
* lisp/vc/vc.el: Require backend 'create-tag' functions to
prompt for the starting point of the branch.
(vc-retrieve-tag, vc-switch-branch): Accept empty NAME only when
not switching branches: it doesn't make sense to switch to the
current branch. Plain 'C-x v r' can still be used to check out
the latest revisions on the current branch.
* lisp/vc/vc-git.el (vc-git--empty-tree): New constant.
(vc-git-diff): When REV1 and REV2 are both nil and there are no
commits yet, diff against the empty tree object (bug#78987).
* lisp/vc/vc-hooks.el (auto-revert-mode): Declare.
(vc-auto-revert-mode): New global minor mode.
(vc-turn-on-auto-revert-mode-for-tracked-files): New function.
* lisp/vc/vc-dispatcher.el (auto-revert-mode)
(auto-revert-buffers): Declare.
(vc-resynch-window): Don't call vc-revert-buffer-internal when
auto-revert-mode will revert the buffer. Call
auto-revert-buffers to ensure that this reversion happens in a
timely manner.
* lisp/vc/vc.el (vc-register): Apply vc-auto-revert-mode to
buffers visiting newly registered files.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Improve the generated docstring.

use 'buffer-file-name' as one of the file names. Properly set
'backup-inhibited' in any file-visiting buffers.
