code only on success.
(vc-exec-after): Ditto.
(vc--inhibit-change-window-start): New variable.
(vc-do-async-command): Use it to allow chaining commands without
moving window point. Return the process instead of the buffer,

(vc-git-pull-and-push): New function.
* lisp/vc/vc.el (vc-pull-and-push): New command (bug#51964).
* lisp/vc/vc-git.el (vc-git--pushpull): Restore handling of

Use the new hook to update compile-command with the edited command.

lines.

use `git apply --cached` to add the patch to the index,

(vc-deduce-fileset-1): Call diff-vc-deduce-fileset in diff-mode.
(vc-next-action): For model 'patch' call vc-checkin with the
diff buffer string.

Call vc-start-logentry with 'patch-string'.
(vc-diff-patch-string): New function.
To be able to use outline-minor-mode-cycle keys in diff-mode,
outline-minor-mode should be higher in minor-mode-map-alist,
and a new variable diff-mode-read-only should be set
when the diff-mode buffer is read-only.
https://lists.gnu.org/archive/html/emacs-devel/2022-01/msg00740.html
* lisp/vc/diff-mode.el: Add diff-mode-read-only to minor-mode-map-alist.
(diff-mode-read-only): New buffer-local variable.
(diff-mode): Set diff-mode-read-only to t when buffer-read-only is non-nil.
Update diff-mode-read-only in read-only-mode-hook.
Remove buffer-read-only from minor-mode-overriding-map-alist.
Remove view-mode-hook because now view-mode is higher than
diff-mode-read-only in minor-mode-map-alist.
* lisp/vc/vc-git.el (vc-git-stash-show):
* lisp/vc/vc.el (vc-diff-internal): Set buffer-read-only to t
before calling diff-mode that will set diff-mode-read-only.
* lisp/vc/vc-git.el (vc-git-use-literal-pathspecs): New variable.
(vc-git-command, vc-git--call): Use it to determine whether to set
GIT_LITERAL_PATHSPECS=1 (bug#51497).
(vc-git--literal-pathspec, vc-git--literal-pathspecs): Remove.
Update all callers. This reverts the previous solution for bug#39452.
* lisp/progmodes/project.el (project--vc-list-files):
Use the new variable.
* lisp/vc/vc-dir.el (vc-dir): Call the backend-specific minor mode
if it exists.

`git version` on macOS returns e.g., "git version 2.30.1 (Apple
Git-130)" and `vc-git--program-version` currently returns "0" instead
of "2.30.1".
* lisp/vc/vc-git.el (vc-git--program-version): Ignore text after
the version number when parsing git versions (bug#52172).
Copyright-paperwork-exempt: yes
* lisp/vc/vc-annotate.el (vc-annotate-show-log-revision-at-line):
Stop from being affected by 'vc-git-print-log-follow'.
* lisp/vc/vc-git.el (vc-git-print-log-follow):
Mention caveats in a comment.
* lisp/vc/vc-git.el (vc-git-register):
Use file names verbatim with 'git update-index', as it only accepts
file names, not pathspecs (bug#39452).
* lisp/vc/vc.el (vc-print-root-log):
Expand ROOTDIR, so that vc-git-print-log doesn't receive an
abbreviated name. Literal pathspecs don't work with those.
* lisp/vc/vc-git.el (vc-git-mode-line-string): Make function more
robust (bug#49683). It could previously error out under certain
conditions, like moving directories in and out of the
VC-controlled tree.
Copyright-paperwork-exempt: yes
* lisp/vc/vc-git.el (vc-git-diff-switches): New defcustom.
(vc-git-print-log): Use it.
* etc/NEWS: Announce the new option.
Copyright-paperwork-exempt: yes
* lisp/vc/vc-dir.el (vc-default-dir-printer): Add check for the
"ignored" status and make 'vc-dir-status-edited' the default face.
Also extend condition for more states that qualify as "warnings".
(vc-dir-ignored, vc-dir-status-ignored): Rename face for consistency.
* lisp/vc/vc-git.el (vc-git-dir-printer): Use the
'vc-dir-status-edited' as the default for the Git backend. And
reference the renamed face. Also stop treating the empty stash
differently from other header values.
* lisp/vc/vc-bzr.el (vc-bzr-dir-extra-headers): Implement new faces.
* lisp/vc/vc-cvs.el (vc-cvs-dir-extra-headers): Same.
* lisp/vc/vc-hg.el (vc-hg-dir-extra-headers): Same.
* lisp/vc/vc-svn.el (vc-svn-dir-extra-headers): Same.
This follows from the discussion in bug#46358.
