Another option which people probably won't like is to have gitweb
start "git check-mailmap --stdin" in the background, leave it running,
and just feed it author/commit info as needed and read back its
replies. The benefit is that you get the .mailmap parsing and
resolution built into Git itself without needing any extra
parsing/resolution Perl code or tests. The downside is that people
might balk at an extra process hanging around for the duration of
gitweb itself. (You could also start up "git check-mailmap" repeatedly
on-demand, but that would probably be too slow and resource intensive
for real-world use.)
