I realized at last why all the treatment functions run on the
whole article buffer.

        * gnus-art.el (article-goto-body-goes-to-point-min-p): New variable.
        (article-goto-body): Use it.
        (gnus-treat-article): Ditto.

gnus-treat-article binds a-g-b-g-t-point-min-p to t, that forces
article-goto-body to go to point-min and return always t.  So,
the article buffer should be narrowed to the body while performing
`(gnus-treat-article nil)' as I did in the trunk.

I see.  I've omitted it in the trunk.  Thanks.
