Make the Article buffer the only buffer. (C-x 1 from within it.)
Now proceed to type several
E [runs the command gnus-summary-mark-as-expirable].
On the last article it really should shift to a blank screen, instead of
replaying that last final article. Which, if the user is not smart, he will
think is just another next article.
