Re: gnus-summary-kill-thread should also do gnus-summary-limit-to-unread

Anyway, try this experiment: go to a newsgroup full of boring articles
and type d d d d ... (gnus-summary-mark-as-read-forward) note that the
view doesn't jerk up until we've d'ed the very last article visible.
It should jerk up when we d the SECOND to last article. That way we
can tell if we are on the last article of a thread or not yet. How to
make it jerk up earlier for all such commands?

Wait, let's explore gnus-auto-center-summary.

Documentation:
*If non-nil, always center the current summary buffer.
In particular, if `vertical' do only vertical recentering.  If non-nil
and non-`vertical', do both horizontal and vertical recentering.

But in Info we see
`gnus-auto-center-summary'
     If non-`nil', Gnus will keep the point in the summary buffer
     centered at all times.  This makes things quite tidy, but if you
     have a slow network connection, or simply do not like this
     un-Emacsism, you can set this variable to `nil' to get the normal
     Emacs scrolling action.  This will also inhibit horizontal
     re-centering of the summary buffer, which might make it more
     inconvenient to read extremely long threads.

     This variable can also be a number.  In that case, center the
     window at the given number of lines from the top.

Assuming the former is correct, I tried both
(setq gnus-auto-center-summary 'vertical)
(setq gnus-auto-center-summary "vertical")
but don't see any magic effect.
(setq gnus-auto-center-summary t) indeed does horizontal recentering
only apparently. Oy vey whatever.
