;;; Commentary:
;;; Bugs:
-;; - VC-dired is either not working or (really) dog slow.
-;; - vc-print-log does not always jump to the proper log entry because
-;; it tries to jump to version 1234 even if there's only an entry
-;; for 1232 (because the file hasn't changed since).
+;; - VC-dired is (really) slow.
