From newsgroup discussion, reproduced with current dev code (the
missing capitalization is a post-3.4.3 buglet):
The orc tries to wield a halberd.
the orc's bow is welded to her hand!
The orc thrusts a halberd. You are almost hit by a halberd.
Caused by overloading polearm attacks with throwing. The monster throwing
code didn't enforce that a polearm must be successfully wielded.
