rev-list: introduce --count option
Add a --count option that, instead of actually listing the commits,
merely counts them.
This is mostly geared towards script use, and to this end it acts
specially when used with --left-right: it outputs the left and right
counts separately. Previously, scripts would have to run a shell loop
or small inline script over to achieve the same. (Without
--left-right, a simple |wc -l does the job.)
