git-shortlog.perl would produce a line with an empty commit title.

This patch fixes that. I believe that just changing the last * to + in the
original regexp would work, but Adrian says it doesn't fix it for him, and
I believe this regexp is way clearer anyway. This is also the original
regexp used before a24e658649170c99fdcb4aaa41545679ad02f755.
