D'oh, sorry, failed to check which was the one used in the last
commits. I'm going to fix this, unless Adam actually prefers the
current way the mapping is done.

The general pattern I've tried to follow in case of multiple email
addresses has been to map everything to the most recent one, but in no
particular order (the order is irrelevant). Apparently in some cases
(such as Adam's) I messed up. :-)

The mailmap intended purpose is to avoid having the same person appear
multiple times in the output of things such as `git shortlog -s -n`.
It doesn't specifically credit contributions to one's employer at a
specific time. For _that_ kind of information, one would rather use
something like `git dm`, for which you can add more sophisticated
metadata about mapping users to companies over time, such as the one
Kenneth shared with us:
