no x-faces in pgnus-0.77

no x-faces in pgnus-0.77

I am not seeing x-faces when using pgnus-0.77.  When I turn on
debugging for gnus-article-display-x-face, I see this backtrace:

* gnus-article-display-x-face()
  byte-code(  [snipped]  )
  gnus-treat-article(nil 1 1)
  byte-code(  [snipped]  )
  gnus-display-mime()
  gnus-article-prepare-display()
  gnus-article-prepare(7658 nil)
  gnus-summary-display-article(7658)
  gnus-summary-next-page(nil)
  call-interactively(gnus-summary-next-page)

and the article is narrowed to its body, not its head.  Could the
problem be in the function gnus-display-mime, and in particular these
lines?

	  (save-restriction
	    (article-goto-body)
	    (narrow-to-region (point) (point-max))
	    (gnus-treat-article nil 1 1)
	    (widen)))

Since gnus-article-display-x-face is being called here (via
gnus-treat-article), the head of the article is missing, so no x-face
header is found.

C-h v gnus-article-treat-xface should return head. Check you have head
and not body or something else.

(setq gnus-treat-display-xface 'head)

is the line that you should have in your .gnus.el

Ah, that did it.  Thanks.  Why doesn't

  (setq gnus-treat-display-xface t)

work?  The variable is supposed to control the display of X-Face
headers, so if it is set to t, shouldn't gnus know enough to look for
them in the head of the message?  Should each treat variable be set up
so that a value of t means 'head or 'body or ..., depending on the
particular variable?

You'd have to ask Lars ;)

Probably, there has been mention of this before, certainly of putting
something in the docs to say to set it to head. Lars did you decide
whether or not gnus should limit acceptable values ?

This is essentially the same problem I had for X-Sent display a few
days ago, with gnus-treat-date-lapsed being t, not 'head.  I would
agree, I think, that certain variables' lack of meaning anywhere *but*
the header means that t and 'head really ought to be the mean thing.

There's some functions that it makes equally as much sense applying to
both headers and bodies, so I don't think that would work.

Well, if a variable makes sense for head only, then t should mean
head.  If it makes sense for body only, then t should mean body.  If
it makes sense for both, then t should mean both.

No?

Perhaps, but I think that's even more confusing.  Setting a variable
to t could then either mean that the function applies to the head, the
body or both, depending on the function.  So I think it's better to
just restrict the customization spec to fit the functions instead.
