Are you thinking that "git remote update default" should only be allowed
if you have configured a group named default?

The old code would allow "git remote update default" and actually do the
same as "git remote update", so I wanted to keep the (possibly unwanted?)
behaviour. If we want to disallow it, we can just do
if (!groups_found && argv != default_argv) instead.
