New submission from Benjamin Giesers:
It would be nice to propagate the formatter_class defined in
argparse.ArgumentParser() to added SubParsers by default. Currently one has to
define the formatter_class for each subparser again and again.
Example:
parser = argparse.ArgumentParser(description='property',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
subparsers = parser.add_subparsers(help='sub-command help')
pcar = subparsers.add_parser('car', help='add car',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
pcar.add_argument('--color', help='color of car', default='red')
pyacht = subparsers.add_parser('yacht', help='add yacht',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
pyacht.add_argument('--length', help='length of yacht [m]', default=12.5)
