Hi Rob and Javier,
Sorry I wasn't clear in my posting. I agree that the way things are
done now isn't correct, and what I'm suggesting is to have
elementary_divisors return the list of prime powers, and
invariant_factors return the m_i's. Rob's suggestion of doing this
within the finitely-genera

I might be a bit slow, but I can't figure out exactly what you want to
change it *to*?
In any event, a (needs-work) patch
