To distinguish the general bulk-move case (where the destination directory was pre-existing) from the directory-rename case (where it was not), the output of raw diff is displayed as "Rnnn a/* b/". Those cannot be confused with renames of files named "whatever/*" with a literal star character, from the full-zero SHA1's.
