32047	Required mutually exclusive groups don't work with boolean arguments.	Mark Gajdosik	Hasan Ramezani	"I have the following management command (called `test.py`):

{{{
from django.core.management import BaseCommand


class Command(BaseCommand):
    def add_arguments(self, parser):
        group = parser.add_mutually_exclusive_group(required=True)
        group.add_argument('--value', type=str)
        group.add_argument('--flag', action='store_true')

    def handle(self, *args, **options):
        pass
}}}

Running `./manage.py test --flag` or `./manage.py --value foo`, the command works as expected. Using `call_command` to call the command from my code fails if I pass `--flag`, e.g.:

{{{
from django.core.management import call_command

call_command('test', flag=True)
}}}

This gets me the following traceback:

{{{
argparse.ArgumentError: argument --flag: ignored explicit argument 'True'
