When I was trying to add the same argument to both the root command and the sub command and you put the arguments before the subcommand, In 2.7.8 the arguments would be parsed correctly. But in 2.7.9, they wouldn't but these arguments would show up in the help doc:(
For python2.7.8

>>> import argparse
>>>
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument("-s", dest="start")
_StoreAction(option_strings=['-s'], dest='start', nargs=None, const=None, default=None, type=None, choices=None, help=None, metavar=None)
>>>
>>> subparsers = parser.add_subparsers()
>>> subparser = subparsers.add_parser("command")
>>> subparser.add_argument("-s", dest="start")
_StoreAction(option_strings=['-s'], dest='start', nargs=None, const=None, default=None, type=None, choices=None, help=None, metavar=None)
>>>
>>> parser.parse_args(["-s", "1", "command"])
Namespace(start='1')

Namespace(start='1')
