New description:
The following produces a error
{{{
E = EllipticCurve([-100,0])
s = E.sha()
s.an_padic(13)
}}}
The error comes from the an_padic asking for only the first constant
coefficient of the p-adic L-series. But it does not harm to compute the
next one too. (This arises only when a twist is involved, otherwise the
the modular symbol at 0 is called directly.)

Comment:
I fixed a few Error syntaxes, too
