[Skills help] circle stab

Syntax: circle 
Syntax: circle behind 

Circle stab is a flanking attack for rogues.  While not as powerful as a
backstab, it can strike home more than once on any given opponent.  Generally 
speaking, a rogue can't circle stab while he's alone, since a circle stab can 
only be performed on a target who is not attacking the rogue himself. Any
weapon used for backstab can be used for circle stab.

By specifying the behind argument, the rogue can target the rearmost person in
the same column as the named victim.
