New submission from Lucas Cimon <[email protected]>:
The test I am going to add to test_argparse.py:
def test_whitespace_help(self):
parser = self._get_parser()
parser.add_argument(
'--foo2', action='store_true', help=' ')
parser.add_argument(
'bar2', type=float, help=' ')
parser.format_help() # raises an IndexError
