The new CLI outputs the status message to stdout for compatibility with the old tool, but it
only does so if the status message is not empty. It should always do that, for the sake of the
newline, so that tests that rely on the blank line to stdout don't fail.

i.e.

        if outs:
            if compat and ret == 0:
                # old cli/mon would send status string to stdout on non-error
                print outs
            else:
                print >> sys.stderr, prefix + outs

should probably be

        if compat:
            if ret == 0:
                # old cli/mon would send status string to stdout on non-error
                print outs
        elif outs:
            print >> sys.stderr, prefix + outs
