Replying to [comment:23 pbruin]:
> I know this isn't ready yet; I was just browsing the branch to see how
many changes need to be made. Are you sure the following is correct? I
think the purpose of the `ellinit()` call is to allow the user to specify
the curve in short Weierstrass form (`ellinit([a, b]) --> y^2 = x^3 + a*x
+ b`).

OK, I see what you mean. We could change it to
{{{
ell = ellinit(ell);
ell = vector(5, i, ell[i]);
}}}
