Comment(by cremona):
That is a sensible suggestion, and if you write a patch I'll review it!
Ideally I would like the code to say "if you know that P is principal and
have a generator, the use it, otherwise...", but I suppose that is what
the uniformizer function might do anyway.
I think that even if we did have a version for Tate's algorithm which
applied directly to an elliptic curve over a local field, I would still
want a global version -- which used generators of prime ideals for fields
of class number 1 at least!
