Ahh, OK.  I didn't know we already had "rev-list --count".

Then please disregard the suggestion to add the option to "log"; it
still holds true that the option does not belong to "shortlog", but
I do think "how many changes were made to this path" statistics
driven by a script should use "rev-list" plumbing, and if it already
has "--count" option, that is perfect ;-)

Thanks.
