tests/readlink.py

keyword: remove "help keyword" from test

Testing help output does not make sense as we have no way to
check for errors in content which would be the only reasonable
test here.

#!/usr/bin/env python

import errno, os, sys

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

sys.exit(0)
