Comment (by pbruin):
Another thing: the method `simon_two_descent()` is currently not quite
consistent between '''Q''' and other number fields: the method over
'''Q''' removes points of finite order from the list (at least since
#5153), but the corresponding method over general number fields does not.
I made the documentation consistent with this, but did not change any
code. If we want to fix this, we can either do it here or make it a
separate ticket.
