* vc.el: Made several backend functions optional.
(vc-default-responsible-p): New function.
(vc-merge): Use RET for first version to trigger merge-news, not
prefix arg.
(vc-annotate): Handle backends that do not support annotation.
(vc-default-merge-news): Removed. The existence of a merge-news
implementation is now checked on caller sites.
* vc-hooks.el (vc-default-mode-line-string): Removed CVS special
case.
* vc-cvs.el (vc-cvs-mode-line-string): New function, handles the
special case that has been removed from the default in vc-hooks.el.

* vc.el (vc-log-edit): Properly handle the case where FILE is nil.
2000-09-05 Andre Spiegel <spiegel@gnu.org>
* vc-hooks.el: Require vc during compilation.
(vc-file-setprop): Use `vc-touched-properties' if bound by the new
macro `with-vc-properties' in vc.el.
(vc-file-getprop): Doc fix.
(vc-after-save): Call `vc-dired-resynch-file' only if vc is loaded.
* vc.el: Require dired-aux during compilation.
(vc-name-assoc-file): Moved to vc-sccs.el.
(with-vc-properties): New macro.
(vc-checkin, vc-checkout, vc-revert, vc-cancel-version,
vc-finish-steal): Use it.
(vc-cancel-version): Moved RCS-specific code to vc-rcs.el. The call
to the backend-specific function is now supposed to do the checkout,
too.
(vc-log-edit): Handle FILE being nil and added a FIXME for log-edit.
* vc-cvs.el (vc-cvs-checkin, vc-cvs-checkout): Don't bother to
set file properties; that gets done in the generic code now.
* vc-rcs.el (vc-rcs-uncheck): Renamed to `vc-rcs-cancel-version'.
Changed parameter list, added code from vc.el that does the
checkout, possibly with a double-take.
* vc-sccs.el (vc-sccs-name-assoc-file): Moved here from vc.el.
(vc-sccs-add-triple, vc-sccs-rename-file, vc-sccs-lookup-triple): Use
the above under the new name.
(vc-sccs-uncheck): Renamed to `vc-sccs-cancel-version'. Changed
parameter list, added checkout command.
(vc-sccs-checkin, vc-sccs-checkout): Don't bother to set file
properties; that gets done in the generic code now.

* vc.el: Docstring fixes (courtesy of checkdoc).
2000-09-05 Stefan Monnier <monnier@cs.yale.edu>
* vc.el (vc-checkout-writable-buffer-hook)
(vc-checkout-writable-buffer): Remove.
(vc-start-entry): Always call vc-log-edit, never vc-log-mode.
(vc-log-mode): Make it into a clean derived major mode.
(vc-log-edit): Mark buffer unmodified (as vc-log-mode did) and use
vc-log-mode if log-edit is not available.
(vc-dired-mode-map): Don't set-keymap-parent yet.
(vc-dired-mode): Do set-keymap-parent here.
(vc-dired-buffers-for-dir): Nop if dired is not loaded.
