Almost 1500 lines of compiler warnings remain, and the GCC developers
are already working on a new version with even more warnings turned on
by default.
Another fix for overwritten messages, this time for potions of monster
detection and magic detection.
I've made the message appear before the display of information, which
may be closer to the originally intended behavior.
Updates to the screen took place in the wrong order, causing messages
and "--More--" prompts to be hidden before they could be seen.
There are probably similar bugs caused by other items.
