Alexz: Wouldn't it be easier to just use the "git shortlog" command? It can show the commit count per author (see my previous post).

The only problem is that the same author can appear under different names (e.g. in the output above: s_nakamoto, Satoshi Nakamoto and --author=Satoshi Nakamoto (which was some command line mistake im sure )). The .mailmap feature might be able to solve this though. See bottom of http://www.kernel.org/pub/software/scm/git/docs/git-shortlog.html
