* 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-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.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.
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...
