	Doc: give an example for a typical entry of `display-buffer-alist'

Hello,

`display-buffer-alist' entries are quite complex.  OTOH, it's not
uncommon that a typical user might need it.  We should give an example
entry, somewhere.

Today, I thought: "I want that *Help* is always displayed in a new frame
when it is not already displayed anywhere".  It took some
time to figure out what was needed:

(add-to-list
 'display-buffer-alist
 '("\\`\\*Help\\*\\'" . ; make *Help* pop up in a new frame when not already displayed
   ((display-buffer-reuse-window display-buffer-pop-up-frame) .
    ((reusable-frames . t)))))

I think something like that should be included as an example somewhere
in the docs - maybe in the documentation of `display-buffer-alist'
itself, maybe in the manual.


Thanks, and regards,

Michael.

I tried to provide an example in revision 110885 on the
Emacs-24 release branch.  Please have a look.

Thanks, martin
