Description
Bernadette Perrin-Riou reports two bugs:
One is that this does not work
sage: E = EllipticCurve("91b") sage: h = E.padic_height(7,10)
The other is that the 2-adic L-series takes gamma to be 1+2 rather than 1+4.

That was quick. I did that part myself already and I am working on the other.

I modified the code for the p-adic L-functions, both ordinary and supersingular. The error bounds should be correct.

Here is first step, for the padic_height.
I am not able to know what to do for gamma.
