[issue28220] argparse's add_mutually_exclusive_group() should accept title and description

[Barry A. Warsaw]

Barry A. Warsaw added the comment:

The workaround is to do something like:

group = parser.add_argument_group(title, description)
me_group = group.add_mutually_exclusive_group()
me_group.add_argument(...blah blah blah...)

Hmm, it might be more complicated than that, so let's ignore 3.6

[issue28220] argparse's add_mutually_exclusive_group() should accept title and description

[Barry A. Warsaw]

New submission from Barry A. Warsaw:

I'd love to sneak this into 3.6, but I can accept being too late.  In any case, 
_MutuallyExclusiveGroup.__init__() should accept title and description 
arguments and pass them to the super class.  Otherwise, you can't great a 
mutually exclusive group that also essentially acts as an argument group.
