If the branch is already laundered and stitched, does nothing.
+=item git-debrebase prepush [--prose=<for commit message>]
+
=item git-debrebase stitch [--prose=<for commit message>]
Stitches the branch,
consuming ffq-prev.
+This is a good command to run before pushing to a git server.
If there is no ffq-prev, it is an error, unless --noop-ok.
