* Small but important fixes needed in existing features:
+** Make vc-checkin avoid reverting the buffer if has not changed after
+ the checkin. Comparing (md5 BUFFER) to (md5 FILE) should be enough.
+
+** Make vc-annotate show place the cursor in the annotate buffer at the
+ same line as the current buffer.
+
** buffer-offer-save should be a permanent local.
** revert-buffer should eliminate overlays and the mark.
