Hi,

the handling of `scroll-margin' has recently changed a bit in Emacs CVS
and recentering seems to happen more agressively now.  This becomes a
problem if `scroll-margin' is greater than 0 and one is scrolling an
article with <RET>.  When the bottom of the article is reached the last
line will not stay at the bottom of the window but jump to the middle of
it.

The recentering is triggered by the statement
(move-to-window-line -1)
in `gnus-article-next-page'.  It is usually countered by
`gnus-article-next-page-1', but not at the end of an article where the
latter function will not be called.

The problem can be circumvented by changing the above statement to
(move-to-window-line (- -1 scroll-margin))

If necessary I can provide a change log entry for such a change.
