Is it possible to find the tick state of the current article, from a
function called from gnus-article-prepare-hook?
I need to check whether the article is unread, or not. I wish to use
u-appt.el to parse messages for Outlook appointment invitations, and I
only want to be prompted for if I wish to save the appointment in the
diary, the first time I read the message.

I tried using gnus-mark-article-hook instead, since this hook is
called from the summary buffer, in what seems to be the appropriate
moment.
But with the code below, I am asked if I wish to save the diary
entry on an unread article. But the article is never marked read.
Looks like my-gnus-check-outlook interfers with
gnus-summary-mark-read-and-unread-as-read, which is the other member
of gnus-mark-article-hook. Hm...
(defun my-gnus-check-outlook ()
"Run from a hook to check new messages in Gnus for Outlook appointment
invitations, and offer to save them in the diary."
(save-excursion
(let ((mark (gnus-summary-article-mark)))
(when (gnus-unread-mark-p mark)
(set-buffer gnus-article-buffer)
(u-appt-check-outlook)))))
(add-hook 'gnus-mark-article-hook 'my-gnus-check-outlook)

Back to gnus-article-prepare-hook.
I tried skipping back to the summary buffer for a peek, in the hope
that the cursor would be positioned at the correct spot. But that
doesn't work. because gnus-summary-article-mark returns `?R' at this
point. Ie. something that will make gnus-unread-mark-p return nil.
(defun my-gnus-check-outlook ()
"Run from a hook to check new messages in Gnus for Outlook appointment
invitations, and offer to save them in the diary."
(save-excursion
(set-buffer gnus-summary-buffer)
(let ((mark (gnus-summary-article-mark)))
(when (gnus-unread-mark-p mark)
(set-buffer gnus-article-buffer)
(u-appt-check-outlook)))))
(add-hook 'gnus-article-prepare-hook 'my-gnus-check-outlook)

The reason this happens, is that when I do
(add-hook 'gnus-mark-article-hook 'my-gnus-check-outlook)
I overwrite the original value of `gnus-mark-article-hook', which is
`(gnus-summary-mark-read-and-unread-as-read)'. This is not what I
expected when calling add-hook. I would expect my new function to be
added to the hook.
I think defcustom's handling of hook variables, is wrong. At least
the way it's done in XEmacs 21.4.
In any case, the below code works for me, for using code in u-appt.el
to scan unread articles in Gnus, for Outlook invitations.
Though I should probably find a less fragile hook, one where the
current mark setting doesn't depend on the position in the hook list.
Here's the code:
(defun my-gnus-check-outlook ()
"Run from a hook to check new messages in Gnus for Outlook appointment
invitations, and offer to save them in the diary."
(save-excursion
(let ((mark (gnus-summary-article-mark)))
(when (gnus-unread-mark-p mark)
(set-buffer gnus-article-buffer)
(u-appt-check-outlook)))))
; Check for Outlook invitations in unread messages
(add-hook 'gnus-mark-article-hook 'my-gnus-check-outlook)
; Add the original value of gnus-mark-article-hook, since this
; is overwritten by the above add-hook.
; Add it at the end, since it sets the mark to read.
(add-hook 'gnus-mark-article-hook 'gnus-summary-mark-read-and-unread-as-read t)
