Modify gnus alist in .gnus. Hook?

[Brady Trainor]

I managed to shorten the group name used in `gnus-group-line-format',
but not sure how to set it up for use in my .gnus.el. 

Either a hook or eval-after-load, but I'm failing on both. 

Here is my modification: 

--8<---------------cut here---------------start------------->8---
(add-to-list 'gnus-group-line-format-alist
             `(?z (gnus-short-group-name gnus-tmp-qualified-group) ?s))
--8<---------------cut here---------------end--------------->8---

A minimal change to the group-line-format would be the z in the
otherwise default: 

--8<---------------cut here---------------start------------->8---
(setq gnus-group-line-format "%M%S%p%P%5y:%B%(%z%)\n")
--8<---------------cut here---------------end--------------->8---

I tried lines like

--8<---------------cut here---------------start------------->8---
(add-hook 'gnus-started-hook
          `(add-to-list 'gnus-group-line-format-alist
                        `(?z (gnus-short-group-name
                              gnus-tmp-qualified-group) ?s))
                              )
--8<---------------cut here---------------end--------------->8---

but this did not work.
