mq: rename next() to nextpatch() to avoid confusing a future check-code patch

next() is a builtin starting in 2.6, so it's also nice to avoid
shadowing the builtin.

#!/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)
