Comment:
This compiled and passed all tests. However if you could shorten the
output or break into multiple lines this doctest in
`schemes/elliptic_curves/heegner.py`:
{{{
sage: k = H.rational_kolyvagin_divisor(D, c); k # long time
(5s on sage.math, 2013)
- (14, 16, 0, 0, ... 0, 0, 0)
+ (2, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 4, 0, 0, 9, 11, 0, 6, 0,
0, 7, 0, 0, 0, 0,...
}}}
Also, is the reason why the other doctest output changes in that file
because the embeddings were negated?
