argparse does not preserve namespace with subparser defaults

was passed and put into the latest release with rather obvious buggy behavior.  

This means that the unittest file does not adequately test for overlapping 'dest' in the main and subparsers.  It probably also does not test many (any?) cases of user provided namespace.

Issue9351 added a test, but it only tested defaults set with 

parser.set_defaults(foo=1)
xparser.set_defaults(foo=2)

not the more common practice of setting defaults in add_argument.

45235 adds one test, but again only for 

xparser.set_defaults(foo=1)

It doesn't test for user inputs, as with

['X','--foo=3']
