The patch that I recently submitted for http://bugs.python.org/issue13922
appears to solve this issue. It only removes the '--' that marked the end of
options.
With:
parser = argparse.ArgumentParser()
parser.add_argument('-f','--foo')
print(parser.parse_args(['-f--']))
print(parser.parse_args(['--foo=--']))
print(parser.parse_args(['-f', '--']))
I get:
Namespace(foo='--')
Namespace(foo='--')
usage: foodash.py [-h] [-f FOO]
foodash.py: error: argument -f/--foo: expected one argument
