vault guard behavior

From the newsgroup:  vault guards would ask your name--and you'd
be able to respond--even when you were unconscious (for any reason
besides fainting from lack of food) or paralyzed.  (The code already
made the guard be forgiving when you failed to promptly follow him
out due to that situation, but it would repeatedly say "move along!"
even though you were unable to move.)
