non-unified diffs. Some functionality moved into `diff-hunk-text' and
`diff-find-text'. Add OTHER-FILE, DRY-RUN, POPUP, and NOERROR
arguments. If DRY-RUN is true, don't actually modify anything. Only
reposition point in the patched file if the patch succeeds. Only pop
up another window if POPUP is true. Emit a message describing what
happened if successful, and at what line-offset. Automatically detect
reversed hunks and do something appropriate.

(vc-sccs-latest-on-branch-p): Add a `FIXME' for a call to the
unknown `vc-latest-version' function. It should probably refer to

functions.

(vc-cvs-retrieve-snapshot): New function (untested).
(vc-cvs-stay-local): Default to t.
(vc-cvs-remote-p): New function and property.

(vc-cvs-checkin): Do a trivial parse to set the state in case of
error. That allows us to get to 'needs-merge even in the
stay-local case. There's still no way to detect 'needs-patch in
such a setup (or to force an update for that matter).
(vc-cvs-logentry-check): Remove, the default works as well.

requested not to use `cvs edit'. And refresh the mode line.
(if
workfile' that got lost when the code was extracted from vc.el.
And merged the tail with the rest of the code (not possible in the
old vc.el where the tail was shared among all backends). And
explicitly set the state to 'edited if `writable' is set.
(vc-cvs-revert,vc-cvs-checkout): References to
`vc-checkout-model' updated to `vc-cvs-update-model'.

the buffer read-write if requested and re-signalling the error.

derives from the old vc-parse-buffer but uses the revision number
rather than the date (much easier to compare robustly).

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

vc-backend-hook-functions.

functions.

locked by somebody else.

vc-sccs-hooks.el and vc-rcs-hooks.el now.
(vc-mode-line-string): New name for former vc-status. Adapted.
(vc-mode-line): Adapted to use the above. Removed optional
parameter.

functions are implementation details of those two backends.

yet; because I guess these callers will disappear into back-end
specific files anyway.

callers.
(vc-checkout-model): Punt to backends.

under `up-to-date'. When NOT verbose and `needs-patch', check out
latest version instead of `merge-news'.

breaks other parts of dired. It is the job of the
backend-specific functions to adjust it temporarily if they need
it.

diff-mode.
