[issue10680] argparse: titles and add_mutually_exclusive_group don't mix (even with workaround)

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

The problem is that the nested group doesn't share/propagate mutually exclusive groups with its parent container. The attached patch fixes this.
