Hi,

You probably see no X-Faces in this article.  The truth is that
Gnus should display two X-Faces; one is in the above header,
another is in the following rfc822 part.  What has occurred is
that the `article-display-x-face' function displayed the X-Face
in the rfc822 part and put the `xface' entry in the
`gnus-article-wash-types' variable at the first time, so the
function removed that face image at the second time.

There's a solution in the following part.  I'd like to do so in
the CVS repository if there aren't better ideas.  Though I think
using the `post-command-hook' is not rather well-mannered, who
reads articles non-interactively? :-p  In addition, I'd also
like to change the `article-display-face' function so that it
can toggle displaying Faces.  How do you think about them?

By the way, I currently have no idea to toggle displaying Faces
in rfc822 parts.  Though it may not be impossible, it will scarcely
be in demand.

P.S.  Is it nonsense if there are two or more Face headers?
