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