I got this wrong, this is not the prompt for the question itself but a
message with the actual answer that is reported afterwards! So we're
fine with both yes-or-no-p and y-or-n-p. Are you aware of any other
interactive case that might be problematic? Are all prompt-like
interactions going ultimately through the same code path?
