I want to tailor some gnus-treat-... settings in group-specific ways.

The obvious approach didn't work: using
`gnus-summary-customize-parameters' (M-C-g) I added a variable
`gnus-treat-hide-citation' with a value of nil:

Variables:
Set variables local to the group you are entering. [More]
[INS] [DEL] Variable: gnus-treat-hide-citation
            Value: nil
[INS]

It seems that the variable gets made buffer-local to the *Summary*
buffer, and it ends up having no effect in the *Article* buffer.

Somewhat disappointed, I cobbled together this awkward alternative:

(add-hook 'gnus-article-mode-hook 'my-gnus-article-mode-hooked)
(defun my-gnus-article-mode-hooked ()
  (and (string= "nnml:bulk.foo" gnus-newsgroup-name)
       (progn
	 (make-variable-buffer-local 'gnus-treat-hide-citation)
	 (setq gnus-treat-hide-citation nil))))

So, two questions:

1. Should the M-C-g way work?  And is the current behavior a bug?
2. Is the gnus-article-mode-hook solution the Right Way?  (Do
   users really have to revert to writing Elisp to do this trivial
   "customization"?)
