gnus-buffer-configuration

[Karl Kleinpaste <karl@lycos.com>]

5.2.25 as supplied with xemacs 19.14.

There is a redundant usage of gnus-use-trees in
gnus-buffer-configuration, in the default `t' case.  There's already a
gnus-use-trees entry under the cond; it's pointless under the `t'.

Much more generally...I am catching up -- 'waaaay up -- from
5.0.something to 5.2.25 now, and I'm finding gnus-buffer-configuration
completely incomprehensible.  Of importance to me, I used to work with
a configuration like this, using a really wide (168-column) emacs:

---------------------
|  Group  |         |   This used to be accomplished with          
|---------|         |	           (gnus-add-configuration         
|         | Article |	            '(article ((group 0.25)        
| Summary |         |	                       (summary 1.0 point))
|         |         |	                      ((horizontal 0.5)    
|         |         |	                       (article 1.0))))    
---------------------

I have a number of (horizontal 0.5) entries, and depend on it pretty
heavily (mail-forward and edit-group are very similar).  The *Info*
documentation on gnus-buffer-configuration is really out of date, in
that it doesn't reference (e.g.) "vertical" as a g-b-c element at all,
even though it's all over the default g-b-c setting in gnus.el.

Could someone provide a clue?  I feel like I'm missing something large
but obvious here.  There are no horizontal examples from which to work
anywhere at this point.
