Committed. I removed the second expected output file, and marked the 
prepared-transactions tests in the schedule as "ignore" instead. That 
way if max_prepared_transactions=0, you get a notice that the test case 
failed, but pg_regress still returns 0 as exit status.

I think it's good enough as it is. I did change the lexer slightly, to 
trim whitespace from the beginning and end of SQL blocks. This cuts the 
size of expected output a bit, and makes it look nicer anyway.
