Per <Someone>'s request, make the game's description of the ``#enhance''
command be the same as in the Guidebook by mentioning spell skills.
Combining weapons plural with spell singular isn't right, but I'm not
sure which way to change that so am leaving it alone.  On the other hand,
the poor grammar used to describe the ``#conduct'' command is easy to fix.
