New issue 78 by aklaing: add_mutually_exclusive_group more than once has
incorrectly formatted help.
http://code.google.com/p/argparse/issues/detail?id=78

What steps will reproduce the problem?
1. Create two mutually exclusive groups: eg

agroup = subcmd_parser.add_mutually_exclusive_group()
agroup.add_argument('--a1', action='store_true', help='blah')
agroup.add_argument('--a2', action='store_true', help='blah')
agroup.add_argument('--a3', action='store_true', help='blah')

bgroup = subcmd_parser.add_mutually_exclusive_group()
bgroup.add_argument('--b1', action='store_true', help='blah')
bgroup.add_argument('--b2', action='store_true', help='blah')
bgroup.add_argument('--b3', action='store_true', help='blah')

What is the expected output? What do you see instead?

Expected output (on running a help command which formats help) is:
[ --a1 | --a2 | --a3 ] [ --b1 | --b2 | --b3 ]

You see instead:
[ --a1 | --a2 | --a3 [ --b1 | --b2 | --b3 ]

Note that the closing brace for the first group is missing.

What version of the product are you using? On what operating system?

1.0.1 on Windows.
