    typing return at the prompt System to patch: beeps and returns.
    It should not allow you to get out without aborting.

It only does this when the buffer you're patching from isn't associated with
a file that is part of any loaded system, since otherwise it knows what system
you want.

In any event, I don't think that I agree (at the moment anyway) that it
shouldn't do what it does.  I don't think it's good policy to have modes
which demand a response and won't let you go; such things can be terribly
confusing for new users of a feature.
