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;SETtest=> COMMIT;WARNING:  COMMIT: no transaction in progressCOMMIT

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.
