On Sep 6 (from the ChangeLog), Lars rewrote the nnkiboze stuff.

A few days late, I upgraded, started Gnus, saw a few group lines appearing
(across the gnu), and then nothing happened.

After a closer look with debug-on-quit I found an old, forgotten nnkiboze group on level 3,
which gnus tried to activate. This nowadays seems to mean: do the kiboze!

Is this intentional ? And if yes, should the lines leak out to the screen ?
