Management command options can be parsed twice.

[mardini]

Under some circumstances, a management command option can be parsed twice, here's an example (I'm aware that --version can be called alone):

$ python manage.py runserver --version
1.8.dev20140524142208
1.8.dev20140524142208

After a quick look, there seems to be two places in core/management/__init__.py where commands options are parsed, both in ManagementUtility.execute():

# First time, via LaxOptionParser()
options, args = parser.parse_args(self.argv)

# Second time
self.fetch_command(subcommand).run_from_argv(self.argv)

I think there should be a check to make sure that once a command option is run, it won't be parsed again.
