That's wrong. Hook elements must be functions (no matter whether named
or anonymous) - but you added an expression that evaluates to a list.
See (info "(elisp) Hooks").
Some more hints (although not crucial): use normal quoting when you
don't need backquote's unquoting (`,'). And there is already an entry
for ?z in the association list, you try to add a second entry for it.
I would do it like this:
--8<---------------cut here---------------start------------->8---
(add-hook
'gnus-started-hook
(lambda ()
(assq-delete-all ?z gnus-group-line-format-alist)
(push '(?z
(gnus-short-group-name gnus-tmp-qualified-group)
?s)
gnus-group-line-format-alist)))
(setq gnus-group-line-format "%M%S%p%P%5y:%B%(%z%)\n")
--8<---------------cut here---------------end--------------->8---
In Emacs 25, there will be a setf'able `alist-get' function that will
make modifying alists a bit more comfortable. Don't care about that
info if you don't know what setf is.
HTH,
Michael.
