I can't see why that function would cause problems.  Isn't it
essentially the same as doing `2 g' in the *Group* buffer?  When I do
that, my groups at levels greater than 2 are not shown any more, but
`3 l' redisplays them, and none of the information is lost.

Moreover, I just checked, and it turns out that I have almost
exactly the same function in my config, being run by the demon,
and it doesn't cause me any trouble.  I'm using git emacs/Gnus.
