I didn't really like this bit, since rev-list has to format the output
only so you can match it.  I realized that I too have written code in
the past to detect which way this goes (in post-receive hooks), and/or
the number of commits as per the request

I hate to get all feature-bloat on you...

But could it state the number of commits as well please? :) :)

So here's an additional patch to provide rev-list logic that supports
this feature.  I have then tweaked your original patch to make use of
it a u+7-5 style.

I'm not too picky about the exact style that it turns out to have in
the end; I have used my own customized version ever since we started
printing a space before the (master *+) dirtiness indicator.  However,
I think we should try to be as unambiguous and short as possible.
Hence I picked the 'u' prefix to avoid ambiguity with the dirtiness
indicator.
