I'm not sure if this is a good use of the mailmap feature.  If someone 
commits under <peter@companyfoo.com> for a while and then later as 
<peter@companybar.com>, and the mailmap maps everything to the most 
recent one, that seems kind of misleading or unfair?  The examples on 
the gitmailmap man page all indicate that this feature is to correct 
accidental variations or obvious mistakes, but not to unify everything 
to the extent that it alters the historical record.
