New submission from David Caro <david.caro.estevez at gmail.com>:

When parsing option like --optionname, --option will match it too


>>> import argparse
>>>  parser = argparse.ArgumentParser()
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('--superstring')
_StoreAction(option_strings=['--superstring'], dest='superstring', nargs=None, const=None, default=None, type=None, choices=None, help=None, metavar=None)
>>> parser.parse_args(['--super','value'])

I'm using argparse 1.1 with python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39), on ubuntu 10.10 32bit
