+;; in a command log buffer. Two other functions, (vc-start-logentry) and
;; (vc-finish-logentry), allow you to associate a command closure with an
;; annotation buffer so that when the user confirms the comment the closure

;; that on-disk files and the contents of their visiting Emacs buffers

-;; When the client mode adds a local mode-line-hook to a buffer, it
+;; When the client mode adds a local vc-mode-line-hook to a buffer, it

;; To do:

-;; - vc-dir-kill-dir-status-process should not be specific to dir-status,
-;; it should work for other async commands done through vc-do-command
-;; as well,
-;;
;; - log buffers need font-locking.
;;
-;; - vc-dir needs mouse bindings.
-;;
-;; - vc-dir toolbar needs more icons.
-;;
-;; - vc-dir-menu-map-filter hook call needs to be moved to vc.el.
