fix "dropping Medusa's corpse down the stairs"

User reported the following incorrect feedback:
	You drop Medusa's corpse.  corpse falls down the stairs.
and apparently thought that the problem was a glitch in the middle of the
sentence; the actual problem is that the second sentence lacks its start.

     This fix isn't perfect.  You'll now get
	Medusa's corpse falls down the stairs.
for the second sentence, but
	The Oracle corpse falls down the stairs.
when dealing with a unique monster who doesn't have a personal name.
Either form seems acceptable to me, but mixing them appears inconsistent.

     Probably all the uses of corpse_xname() (and its callers back up the
chain cxname(), aobjnam(), yobjnam()) need to be reviewed for usage.  I
don't have the energy for that.
