Comment (by pbruin):
It doesn't seem very robust to rely on a duplicate in the list of prime
ideals yielding the ''same'' ''S''-unit twice, rather than two (or more)
different but linearly dependent ''S''-units. PARI's algorithm probably
assumes that the input is a list of pairwise distinct prime ideals, so I
would guess it is safer to apply `uniq()` to the input instead of the
output.
