You probably want to leave funky format alone (and do as the Romans do in this
file), since this is seemingly third party, and you'll want merges to be as
smoother as possible.  I ignored other formatting issues in sibling files.

Done. The formatting of this class is not even consistent with the rest of the
file though.

Now if this is third party, it should live in third_party and not here.
