New SET/autocommit problem

Remember how we make SET/SHOW/RESET _not_ be part of a multi-statement
transaction when it is at the start of a transaction and autocommit is
off?

Well, look at this:

test=> SET random_page_cost = 2;
SET
test=> COMMIT;
WARNING: COMMIT: no transaction in progress
COMMIT

The WARNING happens with SHOW and RESET too. I wonder if we should
suppress the WARNING of a COMMIT with no statements when autocommit is
off. This will probably be better for portability, though again, it is
confusing.
