ui: add method to return option and all sub-options

Apparently ":" has been blessed as a generic separator for
options and sub-options. We formalize this by introducing an API
for obtaining an option and all its sub-options.

This will be used in a subsequent patch for declaring sub-options
for [paths].

#!/usr/bin/env python

import errno, os, sys

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

sys.exit(0)
