Well, I think from _mathematical_ (arithmetic) point of view it makes
perfect sense.  Before you had:

  (rename-of-sub1-file1 rename-of-sub1-file2 rename-of-sub1-file3)

and after you have

  (rename-of-sub1) * (changes in files)

That said, I think that '--group-renames' makes better sense (and is
shorted than '--detect-directory-renames')

+1 for '--group-renames'
