Hi.
I'm not that comfortable with having the python command having such
varying behaviours (especially based on the value of from_tty).

OTOH, if you want to treat it as "a lost cause", an "experiment gone
wrong", or whatever :-), and add commands that don't have that
problem, then I might be ok with it.
