Monks get a big penalty to hit when wearing a suit; otherwise they
get a bonus when not wielding a weapon. But as reported, that lets them
have their martial arts bonus even while wearing a shield which does seem
rather unexpected. This change makes them only get their to-hit bonus
while shieldless as well as weaponless. Impact on play balance is likely
to be quite small; late game characters hardly ever miss due to high luck
bonus and very early game ones won't have found a shield yet.
Shouldn't the "your armor is cumbersome" message be ``if (verbose)''?
