Hi,

I know how to use mailmap to map names to email addresses, however, what if we have some old commits that look like:

commit 1815ccf8ea8a7d99736d9b15c10d2ddf41162faf
Author: ondrej.certik <devnull@localhost>
Date:   Sat Oct 6 01:57:03 2007 +0000

    test for a series bug 364 added, but XFAILed, because sometimes it works, so

commit ef95d618e1fda2dc6b50a0edf343a7b321467527
Author: kirill.smelkov <devnull@localhost>
Date:   Fri Oct 5 20:10:04 2007 +0000

    pprint: add support for multile indexes in unicode mode

commit 7e74ebdf2701f0ab213a6e5ba47b7860fcf90cff
Author: fredrik.johansson <devnull@localhost>
Date:   Fri Oct 5 16:41:04 2007 +0000

    add abc module

E.g. for some reason the addresses are <devnull@localhost>, but the names are correct (svn names). Then "git shortlog -ns" shows things like:

   654  Ondrej Certik
   322  Kirill Smelkov
   268  ondrej.certik
   208  Mateusz Paprocki
    74  fredrik.johansson

is there some way to join "ondrej.certik" with "Ondrej Certik"? If the email address for ondrej.certik was some better one, it'd be easy, but since it's the same for all the old committers, maybe the only way is to rewrite our history and fix this. But I just wanted to check if there is some other way too.

Thanks, Ondrej
