[Domen]

New submission from Domen <ielectric at gmail.com>:

Sample code:

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
>>> parser.add_argument('foo')
>>> parser.parse_args(['-v', '--', '--foo'])
Namespace(foo='--foo', v=True)

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
>>> parser.parse_args(['--', '-f'])
usage: [-h] [-v]
: error: unrecognized arguments: -- -f
