Comment(by wuthrich):
I forgot to add the documentation. The second patch (to be applied after
the first) fixes that.
If check is false and a (or several) presumably-torsion points are given,
the algorithm does not check if they are really torsion anymore. But it
still needs the function .order(). I think we should open another ticket
for this.
Chris.
