revset: leverage orset() to flatten ancestor() arguments

This also makes orset() accept an empty argument because nullary ancestor()
call is valid. That's not the case for orset(), but should be okay.

for f in sys.argv[1:]:
    try:
        print(f, '->', os.readlink(f))
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print(f, '->', f, 'not a symlink')
