Comment(by was):
All patches apply (with a minor rebase) and mostly work. However, there
is one bug.
{{{
Unfortunately, this is wrong, since the coefficients of 1 and T have
to be 0.0000?. However, the output *is* correct to 10 bits of
precision, so the correct fix is just to truncate.::
sage: L = LFunction(EllipticCurve('389a'))
sage: L.taylor_series(RealField(10)(1), 3, proof=True)
-0.00002125? + 0.00001204?*T + 0.75933?*T^2 - 0.43032?*T^3 + O(T^4)
