/* The weapon_check flag is used two ways:
* 1) When calling mon_wield_item, is 2-6 depending on what is desired.
* 2) Between calls to mon_wield_item, is 0 or 1 depending on whether or not
*    the weapon is known by the monster to be cursed (so it shouldn't bother
*    trying for another weapon).
* I originally planned to also use 0 if the monster already had its best
* weapon, to avoid the overhead of a call to mon_wield_item, but it turns out
* that there are enough situations which might make a monster change its
* weapon that this is impractical.  --KAA
