FOUND is set whenever a SELECT INTO returns > 0 rows, *or* when an
INSERT, UPDATE, or DELETE affects > 0 rows. We implemented the first
part of this behavior, but not the second.
I also improved the documentation on the various situations in which
FOUND can be set (excluding inside FOR loops, which I still need to
think about), and added some regression tests for this behavior.

Frank Miles 7-Sep-01. This is really just sticking a finger in the dike.
Frank's case works now, but we still couldn't support a recursive function
returning a set. Really need to restructure querytrees and execution
state so that the querytree is *read only*. We've run into this over and
over and over again ... it has to happen sometime soon.
as well allow DROP multiple INDEX, RULE, TYPE as well. Add missing
CommandCounterIncrement to DROP loop, which could cause trouble otherwise
with multiple DROP of items affecting same catalog entries. Try to
bring a little consistency to various error messages using 'does not exist',
'nonexistent', etc --- I standardized on 'does not exist' since that's
what the vast majority of the existing uses seem to be.
