[with patch, positive review] elliptic curves -- bug in L_ratio()

[cremona]

Nils Bruin reports:

"I ran into the following problem in sage, and I suspect it might be your code:

sage: EllipticCurve([0,0,0,-193^2,0]).sha().an()
[...]
NameError: global name 'misc' is not defined

Was this tested at all?"

It's a problem in L_ratio().

After the attached patch (based on 3.0.4) it works fine:

sage: EllipticCurve([0,0,0,-193^2,0]).sha().an()
4

Does not work with me, did you mean import sage.misc.misc as misc ?

[wuthrich]

Sorry, my mistake; it works of course.

Taking Chris' remark into account I am giving this a positive review.

Cheers,
