Bug report included a pointer to a fix; this patch is a superset.
Gold pieces dropped on an altar by the player got their bknown flag set,
which is incorrect since bless/curse doesn't apply to coins. If a
monster (in reported case, a slain temple priest) dropped gold there too
then the two stacks wouldn't merge. For the normal !GOLDOBJ config, the
problem goes away as soon as the gold gets picked up. I didn't test for
GOLDOBJ but think two inventory slots containing gold can result.
The superset part is to not break agnostic conduct by dropping gold
on an altar since no information is revealed when doing that.
[This was one of the very last patches checked into the old cvs repository,
where the somewhat out of date message above was accidentally omitted.]
