    Revamp stray output check
    
    Keep the content in a file to avoid double lookup.  Also use jat__cmd()
    instead of conditional jat__fail(); that way the number of asserts will
    be consistent.
    
    Also, don't log the stray output as MESSAGE.ERROR; that should be
    reserved for test *errors* (ie. irrelevant to test but invalidating the
    test result).
