subparsers show arguments from the main parser

[jimparis]

With this program:

#!/usr/bin/env python
import argparse
import argcomplete

def c_url(prefix, parsed_args, **kwargs):
    return [ "http://url1", "http://url2" ]

def c_get(prefix, parsed_args, **kwargs):
    return [ "get1", "get2" ]

def c_put(prefix, parsed_args, **kwargs):
    return [ ]

parser = argparse.ArgumentParser()
parser.add_argument("--url", help="URL").completer = c_url
sub = parser.add_subparsers()

get = sub.add_parser("get")
get.add_argument("filename").completer = c_get

put = sub.add_parser("put")
put.add_argument("filename").completer = c_put

argcomplete.autocomplete(parser)
args = parser.parse_args()

Arguments like --url show up after get and put, where they're not allowed:

./test.py get <tab>
expect: get1 get2
actual: --help --url -h get1 get2

./test.py put <tab>
expect: (no suggestions)
actual: --help --url -h

Thanks for reporting (btw, -h/--help are valid completions in your examples, and are still produced after this fix).
