23.0.50; newsticker buffer doesn't refresh

[Toby Allsopp <toby@mi6.gen.nz>]

$ emacs -Q
M-x newsticker-show-news

In the *newsticker* buffer that is now current, movement commands such as
n or <down> appear to have no effect, but the effect becomes apparent
following a C-l.  Alos, the scroll bar is not rendered properly.

I have reproduced this on a trunk build (2007-11-17) without the Debian
patches as well.

The problem doesn't show up on the EMACS_22_BASE branch.
