This patch should not change behavior. It typically omits backslashes
where they are redundant (e.g., in the string literal "^\$").
In a few places, insert backslashes where they make regular
expressions clearer: e.g., replace "^\*" (equivalent to "^*") with
"^\\*", which has the same effect as a regular expression.
Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs,
and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with
RCS IDs, as that makes it clearer that the backslash is intended.
* lisp/progmodes/project.el (project-ignores): New generic
function, and an implementation for the VC project type.
* lisp/progmodes/xref.el (xref--rgrep-command): Split, as a
variant of rgrep-default-command that handles a generic list of
ignores.
(xref-collect-matches): Use it, and pass through to it the value
of the newly added argument.
(xref-find-regexp): Handle ignored paths within the project.
Remove outdated comment.
* lisp/vc/vc.el (vc-default-ignore-completion-table):
Skip the comments and the empty lines.
* lisp/vc/log-view.el (log-view-toggle-entry-display): When
there's no next entry, delete until the end of the buffer.
(log-view-end-of-defun-1): Stop at eob.
* lisp/vc/vc-annotate.el
(vc-annotate-show-diff-revision-at-line-internal): Don't give up
when previous-revision is nil.
* lisp/vc/vc-git.el (vc-git-expanded-log-entry): End the arguments
with `--' to avoid ambiguity.
(vc-git-annotate-extract-revision-at-line): Exclude `^' from the
returned revision string.
(vc-git-annotate-time): Expect `^' before the first revision.
* lisp/vc/vc-git.el (vc-git-diff): Diff against an empty tree if
REV1 is nil, and REV2 is not.
* lisp/vc/vc.el: Update the description of the `diff' function.
* lisp/vc/vc.el (vc-print-log-internal): Pass nil
GOTO-LOCATION-FUNC to vc-log-internal-common when WORKING-REVISION
is not specified.
(vc-incoming-outgoing-internal): Always pass nil.
(vc-log-internal-common): When GOTO-LOCATION-FUNC is nil, don't
call it, and don't set vc-sentinel-movepoint (bug#15322).
(vc-print-root-log): Don't fetch the root working revision, nor
pass it to vc-print-log-internal.
This also removes switch "-C -C" from vc-git-annotate-command.
Fixes: debbugs:17945

(vc-mtn-annotate-command): Use it.
* vc/vc-svn.el (vc-svn-annotate-switches): New defcustom.
(vc-svn-annotate-command): Use it.
* vc/vc.el, vc/vc-hg.el, vc/vc-git.el, vc/vc-hooks.el,
vc/vc-mtn.el, vc/vc-rcs.el, vc/vc-sccs.el, vc/vc-src.el: rrollback
method removed, to be replaced in the future by uncommit.
* vc.el, all backends: API simplification: Remove 4th 'default-state'
argument from vc-dir-status files and its backend methods - no backend
method ever set it. It was used only in the fallback method to to set
a default of 'up-to-date, though a convoluted call chain obscured
this.
* vc/vc.el and all backends: API simplification; clear-headers is no
longer a public method. It is now local to the one place it's used,
in the RCS steal-lock method.
* lisp/vc/vc.el (vc-find-conflicted-file): Look for conflicted files in the
current "project" rather than just the current directory.
* lisp/vc/vc-git.el (vc-git-conflicted-files): Clarify in which directory
the file names make sense.
* vc/vc.el, vc/vc-cvs.el, vc/vc-rcs.el, vc/vc-svn.el: The 'merge'
backend method of RCS/CVS/SVN is now 'merge-file', to contrast with
'merge-branch'. Prompting for merge revisions is pushed down to the
back ends; this fixes a layering violation that caused bad behavior
with SVN.
* vc/vc.el, vc-hooks.el, and all backends: API simplification;
vc-stay-local-p and repository-hostname are no longer public
methods. Only the CVS and SVN backends used these, and the SVN
support was conditioned out because svn status -v is too slow.
The CVS back end retaiin this machibery and the vc-stay-local
configuration variable now only affects it.
* vc/vc.el, vc-hooks.el, and all backends: API simplification;
vc-state-heuristic is no longer a public method, having been removed
where it is redundant, unnecessary, or known buggy. This eliminated
all backends except CVS. Eliminates bug#7850.
* vc/vc-cvs.el, vc/vc-hooks.el, vc/vc-rcs.el, vc/vc-sccs.el: Eliminate
vc-mistrust-permissions. It was only relevant to the RCS and SCCS
back ends and defaulted to t. Code now always mistrusts permissions -
by actual measurement the effect on performance is negligible. As a
side effect bug#11490 is now irrelevant.
* vc/vc.el, vc-hooks.el, and all backends: API simplification;
vc-workfile-unchanged-p is no longer a public method (but the RCS and
SCCS back ends retain it as a private method used in state
computation). This method was redundant with vc-state and usually
implemented as a trivial call to same. Fixes the failure mode
described in bug#694.
This hasn't made any sense since RCS, and was a dumb stunt then.
* vc/vc.el and all backends: API simplification; init-revision is
gone, and vc-registered functions no longer take an initial-revision
argument.
* vc-filewise.el: New file to isolate code used only by the
file-oriented back ends (SCCS/RCS/CVS/SRC) which should not live in
vc.el and certainly not in vc-hooks.el.
Alters vc/vc-bzr.el, vc/vc-cvs.el, vc/vc-dav.el, vc/vc-git.el,
vc/vc-hg.el, vc/vc-mtn.el, vc/vc-rcs.el, vc/vc-sccs.el,
vc/vc-svn.el, vc/vc.el.
where this matters (which is only in SCCS and RCS) files are now always
checked out editable. This may actually have been dynamically true
already - it looks like the vc-next-action code evolved past visiting
the other case. Tested with RCS.
Alters vc/vc-arch.el, vc/vc-bzr.el, vc/vc-cvs.el, vc/vc-dav.el,
vc/vc-git.el, vc/vc-hg.el, vc/vc-mtn.el, vc/vc-rcs.el,
vc/vc-sccs.el, vc/vc-svn.el, vc/vc.el.
Only the RCS, SCCS, and CVS back ends tried to do anything with it,
and that code was never exercised. Chiseling away the cruft of
decades...
lisp/vc/vc.el (vc-retrieve-tag): Doc fix.
doc/emacs/maintaining.texi (Switching Branches): Mention "C-x v r".
Correct commands for switching branches in various VCSs.
(vc-print-log-internal): Use cl-some.
* lisp/vc/vc-git.el (vc-git-region-history): New function.
(vc-git-region-history-mode-map)
(vc-git--log-view-long-font-lock-keywords)
(vc-git-region-history-font-lock-keywords): New vars.
(vc-git-region-history-font-lock): New function.
