$ git log -p | git shortlog Documentation/
is also a nonsense request. When outside a repository, i.e.
$ git -C $path_to_repo | git shortlog Documentation/
is not giving any revisions, so the error message should not say "no
revisions can be given"---a nitpicky bug reporter would say "I gave
no revisions, why are you complaining to me?"
