New submission from Rémi Rampin:
This works correctly on Python 3.4.
On Python 2.7, argparse seems to completely and silently ignore arguments in
some conditions, for instance this setup will cause --verbose to be ignored on
the main parser:
options = argparse.ArgumentParser(add_help=False)
options.add_argument('-v', '--verbose', action='store_true')
parser = argparse.ArgumentParser(parents=[options])
subparsers = parser.add_subparsers()
parser_cmd = subparsers.add_parser('cmd', parents=[options])
Full runnable example here:

Might or might not be related to #9351, workarounds welcome.
