When using a fountain or throne, getting a --More-- prompt
usually means that you're about to be told that it has just dried
up or vanished. But since that topology change didn't occur until
after the message, players could cheat by forcing SIGHUP instead
of answering the prompt; the resulting save file would retain the
original topology. So change the dungeon prior to telling the user
about it.
The `fixes' entry possibly belongs in the tty-specific category
but since the change is to core code I put it in the general section.
<Someone> reported that dowaternymph and dowaterdemon did not print a message
when their G_GONE checks failed. Now they do. I wasn't feeling
imaginative, so the the dowaterdemon message is the same as for no snakes.
This patch, based on code sent to us by <Someone> well over a year ago, addresses
bugs recently resurfaced. Namely, that lava does not generally do anything
to monsters or objects that land in java. Newly renamed minliquid() handles
both water and lava, and new fire_damage() is used similar to water_damage().
