The saturation() method for elliptic curves of Q has a small bug: a variable (which will most often notbe used) was not initialised. At the same time I changed two parameter in the saturation code.

  • Status changed from new to needs_review

I have been using this code (with the patch) for many thousands of curves over several months. I no longer remember which curve actually triggered the bug, so I have not added a doctest. WIth a new release I realised that I had never submitted the patch for review (but I will go on using it every day even if reviewers don't like the lack of doctest!).
