Ok, that would be workable. Gnus could transmogrify that list to
(lambda (g1 g2)
(or (gnus-group-sort-by-unread g1 g2)
(and (not (gnus-group-sort-by-unread g2 g1))
(gnus-group-sort-by-level g1 g2))))
and give that as the predicate to sort. Won't this give you the same
results as first using `gnus-group-sort-by-level' as a predicate and
then `gnus-group-sort-by-unread' as a predicate for sort?
I have no idea whether it will be faster, though...
(`gnus-group-sort-by-level' should really be called
`gnus-group-level-less' or something since it is a `less' function and
not an actual sorting function...)
