Following the recent threads on notebook features, some thoughts on notebook

Hi all,
We recently ran into two cases of confusing behaviour of Factorization

The first:

sage: f^2

I traced this to a special case in the powering code for taking powers
of zero, which f is treated as:
sage: bool(f)
False
This is because f.__len__()

Hi,
I traced this down to integral_elements_with_trace not handling the
signs in pari's output of qfminim properly. It will only return a single
element from each pair of conjugates, and depending on
F.reduced_basis(), it might miss elements in ZZ with the required trace
entirely.
