/* The weapon_check flag is used two ways:
9
* 1) When calling mon_wield_item, is 2-6 depending on what is desired.
10
* 2) Between calls to mon_wield_item, is 0 or 1 depending on whether or not
11
* the weapon is known by the monster to be cursed (so it shouldn't bother
12
* trying for another weapon).
13
* I originally planned to also use 0 if the monster already had its best
14
* weapon, to avoid the overhead of a call to mon_wield_item, but it turns out
15
* that there are enough situations which might make a monster change its
16
* weapon that this is impractical. --KAA
