I did think about that and decided not to do it (in fact the first
revision of this patch did exactly that).

If we have to maintain this list manually, we might as well leave to
the place that matters: the completion script. I don't think the
person who updates send-email.perl would be always interested in
completion support. And the one that is interested usually only looks
at the completion script. Putting this list in send-email.perl just
makes it harder to find.
