(vc-rcs-checkin, vc-rcs-checkout): Don't set all properties.
(vc-rcs-register): If there is no RCS subdir, ask the
user whether to create one.
(vc-rcs-state-heuristic): Use
file-ownership-preserved-p.
(vc-rcs-checkout): Remove the error-handling for missing-rcs.
(vc-rcs-state-heuristic): Don't use file-writable-p.
(vc-rcs-print-log): Insert in the current buffer.
(vc-rcs-diff): Insert in the current buffer and remove unused arg
CMP.
(vc-rcs-workfile-unchanged-p): Use vc-do-command
instead of vc-simple-command.
(vc-rcs-fetch-master-state): Removed check for unlocked-changes to
avoid doing a diff when opening a file.
(vc-rcs-state): Added check for unlocked-changes.
(vc-rcs-header): Escape Id.
(vc-rcs-workfile-unchanged-p): Remove optional arg VERSION.
(vc-rcs-state): Call vc-workfile-unchanged-p, not the RCS-specific
version.
(vc-rcs-state-heuristic): Use file-writable-p instead
of comparing userids.
(vc-rcs-fetch-master-state): Handle the case where rcs is missing.
Simplify the logic by eliminating unreachable code.
(vc-rcs-diff): Only pass `2' to vc-do-command if necessary and
just do a recursive call if we need to retry.
(vc-rcs-checkout): Handle the case where rcs is missing by making
the buffer read-write if requested and re-signalling the error.
(vc-rcs-find-most-recent-rev): New function.  The code
derives from the old vc-parse-buffer but uses the revision number
rather than the date (much easier to compare robustly).
(vc-rcs-fetch-master-state): Use `with-temp-buffer'.  Adapt to the
new vc-parse-buffer (and vc-rcs-find-most-recent-rev).  Find the
locking-user more directly.  Check strict locking and set
checkout-model appropriately.

(vc-rcs-latest-on-branch-p): Use with-temp-buffer and adapt to the
new vc-parse-buffer (and vc-rcs-find-most-recent-rev).

vc-parse-buffer.

file name and workfile version.

vc-rcs-minor-part, vc-rcs-previous-version): Remove duplicates.

call to vc-rcs-latest-on-branch-p.  Hopefully that was the right
one.
(vc-rcs-steal-lock): Renamed from `vc-rcs-steal'.
 Updated everything to use `vc-checkout-model'.
(vc-rcs-backend-release-p): function added.  other
