Comment (by vbraun):
The old `EllipticCurve_from_cubic` just computed the Jacobian using Magma.
So, strictly speaking, we replace the wrong output with the correct
output. Its intentionally backwards incompatible.
I don't particularly like adding extra keyword arguments to
`EllipticCurve` that only make sense in very special circumstances. If you
want to reduce the number of global symbols, which I'm all in favor of,
then one should combine the constructors into a class
`EllipticCurve.from_foobar()` to disambiguate.
That'll also fix your last problem that the HTML hyperlinks don't
translate particularly well into the text-mode help.
