Comment (by ncohen):
Hello,
I just opened the branch to see what it does (I do not understand anything
of the math involved here) and I noticed this change:
{{{
- if not (i is None):
+ if i > 0 and not (i is None):
}}}
If `i` can be equal to `None`, you should probably write {{{not (i is
None) and i > 0}}} instead (i.e. reverse the conditions).
