  29 commit messages have the form '<action> <new-patch-id>'. The <action>
  30 can be one of the following:
  31
  32   new     - new patch created
  33   refresh - local changes were added to the patch
  34   push    - the patch was cleanly pushed onto the stack
  35   push(m) - the patch was pushed onto the stack with a three-way merge
  36   push(f) - the patch was fast-forwarded
  37   undo    - the patch boundaries were restored to the old values
  38
  39 Note that only the diffs shown in the 'refresh' and 'undo' actions are
  40 meaningful for the patch changes. The 'push' actions represent the
  41 changes to the entire base of the current patch. Conflicts reset the
  42 patch content and a subsequent 'refresh' will show the entire patch."""
