Yes, there are other ways to fix this --- but this is the cleanest, and
I think cleans up some surprising functionality.  We cleaned up some
suprises in 7.3 (pg_atoi), and if we don't do cleanups like this, we
accumulate a system that behaves eratically --- as you showed in the
original report of psql -c not working for autocommit off.
