Subject: Add message for failed fountain monster detection
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bf53ff9de58247242cdc60afe448c3f43e4bc097;p=nethack

Add message for failed fountain monster detection

When the fountain quaffing monster detection effect was triggered on a
level without any monsters, no message would be printed.  I think this
was the only scenario where drinking from a fountain wouldn't print
anything, so it stood out as unusual.

Print a messsage in the case monster detection fails, to make it
consistent with other fountain effects and ensure it's clear the hero
did still drink from the fountain on that turn.  I used "the water
tastes like nothing" for the (sort of tenuous) connection to there being
nothing living on the level, but there might be a better message to put
in there.
