New issue 54 by ianbicking: When using subcommands, option in parent parser
should be placeable anywhere
http://code.google.com/p/argparse/issues/detail?id=54

I have a command with a bunch of subcommands. In the parent parser I added
a verbose option. I can do:

mycommand --verbose subcommand --something

But I expect to also be able to do this:

mycommand subcommand --verbose --something

But... I can't.

That's intentional because it's possible you might want those two --verbose
flags to
mean different things. If you want them to mean the same things, I'd
suggest using a
parent parser:

verbose_parser = argparse.ArgumentParser(add_help=False)
verbose_parser.add_argument('--verbose', action='store_true')

parser = argparse.ArgumentParser(parents=[verbose_parser])
subparsers = parser.add_subparsers()
foo_parser = subparsers.add_parser('foo', parents=[verbose_parser])

That should allow the same --verbose flag to be specified in either parser.

Should this work with sub-parsers? I am not seeing the parents option as a
valid option to either .add_subparsers() or .add_parser().
