Hi there,

in Bug#25946 we discussed how to replace the obsolete variables
special-display-buffer-names and special-display-regexps.  The
attached patch extends the doc string of display-buffer-alist based
on that discussion.

Best wishes

Subject: [PATCH] Improve documentation for display-buffer-alist

The obsolete variables special-display-buffer-names and
special-display-regexps refer to display-buffer-alist.  As a follow-up
to Bug#25946 this change extends the doc string for that variable.
* list/windows.el (display-buffer-alist): Extend doc string.
