requiring it leads to a recursive loading of vc.el and vc-hooks.el
during bootstrap.

	* vc.el: (toplevel): Don't require `dired' at run-time.
	(vc-dired-resynch-file): Remove autoload cookie.

2000-09-05  Andre Spiegel  <spiegel@gnu.org>

	* 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.

2000-09-05  Stefan Monnier  <monnier@cs.yale.edu>

	* 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.

don't support anything else under SCCS yet.
(vc-sccs-update-changelog): Dummy implementation that
simply signals an error.
(vc-sccs-state-heuristic): Use
file-ownership-preserved-p.
(vc-sccs-workfile-unchanged-p): Fix call to
vc-do-command.
(vc-sccs-state-heuristic): Don't use file-writable-p.
(vc-sccs-workfile-unchanged-p): Fix parenthesis.
(vc-sccs-print-log, vc-sccs-diff): Insert in the current buffer.
(vc-sccs-workfile-unchanged-p): Rewritten.
(vc-sccs-diff): Remove optional arg CMP.
(vc-sccs-state): Call vc-workfile-unchanged-p, not the
SCCS-specific function.
(vc-sccs-state): Fix obviously wrong parenthesis.
(vc-sccs-state-heuristic): Use file-writable-p instead of
comparing userids.
(vc-sccs-checkout): Use `unless'.
(vc-sccs-state): Use with-temp-buffer.
(vc-sccs-workfile-version): Use with-temp-buffer and new
vc-parse-buffer and don't bother setting the property.
(vc-sccs-add-triple): Use with-current-buffer and
find-file-noselect.
(vc-sccs-lookup-triple): New vc-parse-buffer and turn cond -> if.
 Merge in
code from vc-sccs-hooks.el.
(vc-sccs-release, vc-sccs-system-release): Remove.  Don't require
'vc anymore.
(vc-sccs-responsible-p): Use expand-file-name instead of concat
and file-directory-p instead of file-exists-p.
(vc-sccs-check-headers): Simplify the regexp.
(vc-sccs-responsible-p, vc-sccs-register): Use
`vc-sccs-search-project-dir' instead of `vc-sccs-project-dir'.
(vc-sccs-header): New var.
(vc-sccs-rename-file): Renamed from
vc-sccs-record-rename.  Use `find-file-noselect' rather than
`find-file' and call `vc-rename-master' to do the actual move.
(vc-sccs-diff): Remove unused `backend' variable.
(tail): Provide vc-sccs.
(vc-sccs-checkout): Removed call to
vc-file-clear-masterprops.  If writable, set vc-state to 'edited

(vc-sccs-register-switches): New var, copied off of vc-rcs-hooks.
(vc-sccs-latest-on-branch-p): Add a `FIXME' for a call to the
unknown `vc-latest-version' function.  It should probably refer to
vc-workfile-version or somesuch, but it's very unclear to me and I
don't have SCCS to test things.
(vc-sccs-steal-lock): Renamed from `vc-sccs-steal'.
(vc-BACKEND-responsible-p): New
functions.
(vc-BACKEND-register): Renamed from `vc-BACKEND-admin'.  Removed
query option.  Redocumented.
(vc-sccs-diff): Function changed name from
`vc-backend-diff'.  This makes `vc-diff' work.
(vc-sccs-release): Doc fix.
(vc-sccs-admin): Added the query-only option as
required by the vc.el file.
(vc-sccs-latest-on-branch-p): Function added.
