Comment (by cremona):
Thanks a lot for tidying various things up ( at least some of which were
not introduced by me, I think!).
We do need someone with a good knowledge of isogenies to check this. In
writing the code I had to work out quite a lot of mathematics for which I
do not know a good source (in the CM and potential CM cases). I am
actually using the code a lot all the time now, on many thousands of
curves, which is a good test, but the field degrees are small.
