Testing a forthcoming extension of monsters using wands of undead
turning revealed a couple of pre-existing bugs. Previously only
noticeable if hero zaps self or breaks a wand of undead turning so
unlikely to have happened much.
"Your <mon> corpse comes alive" was given even if it was revived
as an undead. Also, it was "your <mon> corpse" instead of "one of
your <mon> corpses" even when one from a stack was involved. If
done by hero to self that message follows "one of your <mon>
corpses glows iridescently" so the comes alive message was ok but
verbose. Change that to "it comes alive" or "it reanimates" when
following the glow message.
