You won't have to do anything. With the code as it is, the dummy group
is present at Gnus startup, but gets deleted on first save. I'll put in
a fix that makes sure it doesn't get deleted. That should take care of
things.

There's no longer any need for a dummy group, and in the long run it
would be good to get rid of it. But I think in short term we still think
there's a significant amount of out-of-tree code that might be expecting
a dummy group.
