(vc-annotate-display): Removed arguments BUFFER and BACKEND.
Added argument OFFSET. Instead of backend function, calls now
generic `vc-annotate-difference'.
(vc-annotate-difference): Added as generic function instead of
backend-specific function. No longer takes argument POINT, but
instead accepts a time OFFSET.
(vc-default-annotate-current-time): Added.
New functions.
(vc-version-diff): Use them. As a result, coding systems are now set
up properly for all sorts of diffs, and tree diffs can now also be
done locally.
(vc-diff): With a prefix argument, don't require that it's called from
a buffer under version control.
set it up and don't erase it. Updated doc string to reflect that.
(vc-version-diff): When doing a single file diff, don't switch to the
*vc-diff* buffer before the command. This is to preserve local variable
bindings that might affect the diff command.
(vc-print-log): Don't switch to the *vc* buffer before the command, so
that local variable bindings are preserved.
use vc-make-version-backup to actually make the backup.
(vc-version-other-window, vc-version-backup-file): Handle both
automatic and manual backups.
(vc-revert-file): Use vc-delete-automatic-version-backups to get rid
of all of them.
(vc-checkout, vc-finish-steal, vc-checkin, vc-revert-file):
Update call to with-vc-properties accordingly.
(vc-comment-search-reverse, vc-comment-search-forward): Docstring fix.
(vc-revert-buffer): Be more careful about window selection and deletion.
(vc-switch-backend): Slight reorg to avoid calling `registered' twice.
(vc-version-backup-file): New function.
(vc-checkout): Create a version backup if necessary.
(vc-checkin): If a version backup file exists, delete it.
(vc-version-diff): Diff locally using version backups, if available.
(vc-revert-file): If there's a version backup, revert locally.
(vc-transfer-file): Use version backup for base version, if
available. If not, ask for confirmation whether to get it from the
server. Update mode line before check-in.
list. Handle multiple backends correctly.
(vc-find-new-backend): Function removed.
(vc-register): Use vc-responsible-backend, as before.
(vc-next-action-on-file): Do use vc-registered, not vc-backend.
Use vc-backend rather than vc-registered.
(vc-next-action-on-file): Use intern-soft.
Deal with read-only *vc-diff* buffer.
(vc-switch-backend): Short circuit if nothing is to be done.
Handle the case where (not (memq backend backends)).
Don't use vc-resynch-buffer which could lose unsaved editing.
(vc-transfer-file): Docstring fix.
(edit-vc-file, vc-next-action-on-file): Don't use find-file.
(vc-find-new-backend): New function split from vc-responsible-backend.
(vc-register): Use it.
(vc-responsible-backend): Remove REGISTER arg and add BACKENDS arg.
(vc-unregister): Drop BACKEND arg (it doesn't work anyway).
(vc-default-unregister, vc-revert-buffer): Docstring fix.
(vc-clear-headers): Don't use find-file.
(vc-revert-buffer): Use `and' again (must have been a braino).
(vc-switch-backend): Only prompt if requested.
(vc-default-receive-file): Update call to vc-unregister.
* vc-rcs.el (vc-rcs-unregister): Keep a backup of the master file.
(vc-rcs-receive-file): Avoid with-vc-properties.
Update call to vc-unregister.
Use constant `RCS' rather than (dynamically bound) var `backend'.
(vc-start-entry): New argument initial-contents. Don't visit the file
if it isn't already visited. Brought documentation up-to-date.
(vc-next-action, vc-register): Updated calls to vc-start-entry.
(vc-checkin): New optional arg initial-contents, which is passed to
vc-start-entry.
(vc-finish-logentry): Make sure to bury log buffer only if there
really is one. Call `vc-resynch-buffer' on log-file, not
buffer-file-name.
(vc-default-comment-history, vc-default-wash-log): New functions.
(vc-index-of): Removed.
(vc-transfer-file): Make do without the above.
(vc-default-receive-file): Call comment-history unconditionally. Pass
the resulting string to vc-checkin, instead of inserting it into the
