(vc-fetch-master-properties): CVS case: Use it.
(vc-lock-from-permissions, vc-file-owner, vc-rcs-lock-from-diff):
New functions.
(vc-locking-user): Largely rewritten. Uses the above, handles RCS
non-strict locking. Under CVS in CVSREAD-mode, learn the locking state
from the permissions.
(vc-find-cvs-master): Use vc-insert-file, rather than
find-file-noselect. Greatly speeds up things.
(vc-consult-rcs-headers): Bug fix, return status in all cases.
(compilation-sentinel): If compilation-exit-message-function is non-nil,
call it to produce messages for buffer and mode line.
(grep): Use that variable to produce snazzier messages.
added, but not yet committed.
(vc-backend-checkout): RCS case: In non-strict locking mode, force to
overwrite the writable workfile. CVS case: Do the right thing in
CVSREAD-mode.
CVS case: new state `locally-added'.
(vc-locking-user): Under RCS with non-strict locking, don't trust
the file permissions. CVS case: change which states count as
"locked".
(vc-consult-rcs-headers): Streamlined. Don't set vc-locking-user if
this is called under CVS. Under RCS, use a heuristic to find the
value of vc-checkout-model without examining the master file.
(vc-parse-locks): Set vc-checkout-model.
(vc-status): Comment change.
(vc-after-save-hook, vc-after-save): The former renamed to the
latter. Now unconditionally called by `basic-save-buffer', determines
whether the buffer should be "locked" or not.
(vc-mode-line): No longer use dynamic after-save-hook. Changed
references to `automatic' into `implicit'.
(vc-checkout-model): Values are now `manual' and `implicit'. Derive
the property on a per-file basis, supporting all possible modes.
(makefile-define-space-face): New function.
(makefile-tab-face): Variable deleted.
(makefile-define-tab-face): Function deleted.
(makefile-font-lock-keywords): Highlight leading spaces, not tabs.
(vip-read-string-with-history): minibuffer-setup-hook no longer
waits for the user to type, if there are unread events.
Harnessed view-minor-mode.
Added (vip-leave-region-active) to all simple movement commands.
since `newline-and-indent' doesn't either. Don't turn a trailing
quoted tab into a space.
(sh-mode): Use new `skeleton-newline-indent-rigidly'.
(sh-set-shell): Make maximum font-locking also hightlight keywords
after ``' and `!'. (The latter is for ksh '93 but should't hurt other
shells.)
