This is another one of those bits where it's mostly a question of whether
it's helpful to accept random stuff and make a good guess at what it was
supposed to mean, or whether it's better to be strict and give an error
message. My inclination would be to keep supporting -12, which is one of
those things that feels like "should" be part of the protocol even if it
isn't. The rest seem like syntax errors to me, and I'm not sure we're
doing anyone any favors by blindly applying scanf.

Yeah, that would be better.

Yes, 501 seems more appropriate for both of those to me.
