Comment (by vbraun):
I thought about whether to return both when `transformation=True` when I
wrote the code originally, but then decided against it. Its not
particularly natural the way the computation goes. If speed is an issue
(and its at worst a factor 2x for calling `WeierstrassForm` twice, and in
reality its much faster to compute the Weierstrass form without
transformation) then you should parametrize the coefficients and derive
the formula in one step. So there isn't really any justification.
Reviewer patch looks good to me.
