+;; If provided, this function is used to find the version control
+;; state of as many files as possible in DIR, and all subdirectories
+;; of DIR, in a fast way; it is used to avoid expensive indivitual
+;; vc-state calls. The function should not return anything, but
+;; rather store the files' states into the corresponding properties.
+;; Two properties are required: `vc-backend' and `vc-state'. (Note:
+;; in older versions this method was not required to recurse into
+;; subdirectories.)
;;
;; * working-revision (file)
;;
;; used for files under this backend, and if files can indeed be
;; locked by other users.
;;
+;; - modify-change-comment (files rev comment)
+;;
+;; Modify the change comments associated with the files at the
+;; given revision. This is optional, many backends do not support it.
+;;
;; HISTORY FUNCTIONS
;;
;; * print-log (files &optional buffer)
;; to your backend and which does not map to any of the VC generic
;; concepts.
+;;; Todo:
+
+;; - Make vc-checkin avoid reverting the buffer if has not changed
+;; after the checkin. Comparing (md5 BUFFER) to (md5 FILE) should
+;; be enough.
+;;
+;; - vc-update/vc-merge should deal with VC systems that don't
+;; update/merge on a file basis, but on a whole repository basis.
+;;
+;; - the backend sometimes knows when a file it opens has been marked
+;; by the VCS as having a "conflict". Find a way to pass this info -
+;; to VC so that it can turn on smerge-mode when opening such a
+;; file.
+;;
+;; - the *VC-log* buffer needs font-locking.
+;;
+;; - make it easier to write logs, maybe C-x 4 a should add to the log
+;; buffer if there's one instead of the ChangeLog.
+;;
+;; - make vc-state for all backends return 'unregistered instead of
+;; nil for unregistered files, then update vc-next-action.
+;;
+;; - add a generic mechanism for remembering the current branch names,
+;; display the branch name in the mode-line. Replace
+;; vc-cvs-sticky-tag with that.
+;;
+;; - vc-register should register a fileset at a time. The backends
+;; already support this, only the front-end needs to be change to
+;; handle multiple files at a time.
+;;
+;; - add a mechanism to for ignoring files.
+;;
+;; - deal with push/pull operations.
+;;
+;; - decide if vc-status should replace vc-dired.
+;;
+;; - vc-status needs a menu, mouse bindings and some color bling.
+;;
+;; - vc-status needs to show missing files. It probably needs to have
+;; another state for those files. The user might want to restore
+;; them, or remove them from the VCS. C-x v v might also need
+;; adjustments.
+;;
+;; - "snapshots" should be renamed to "branches", and thoroughly reworked.
+;;
+;; - do not default to RCS anymore when the current directory is not
+;; controlled by any VCS and the user does C-x v v
+;;
