Pull request from vultur-cadens: when engraving with a weapon, the
occupation routine doesn't dull it on the last character, so engraving
a single character never dulled the weapon. Didn't apply to engraving
with other types of items.
Closes #651
after changes to gender tracking for corpses and statues, when a unique
monster got turned into a statue if was erroneouly flagged as female
rather than 'historic'
+changing engraving to an occupation resulted in not dulling a weapon used to
+ engrave a single character
curses: 'msg_window' option wasn't functional for curses unless the binary
also included tty support
