        # cause one of the exceptions being caught. Therefore, look for an
        # exact match. (e.g. salt -L foo test.ping)

    # We should never get here based on the return statements in the logic
    # above. If we do, it is because something above changed, and should be
    # considered as a bug. Log a warning to help us catch this.
