Please try a "wide reply", "reply to list" or "reply to all" to this

What Eli meant was more or less

(setq display-buffer-alist '(("\\*Buffer List\\*" nil (inhibit-same-window . t))))

But this is still problematic because it will disallow reusing a window
that already shows the buffer list.  Even if you explicitly ask for it
as in

(setq display-buffer-alist
      '(("\\*Buffer List\\*"
      display-buffer-reuse-window (inhibit-same-window . t))))

it won't work when you do C-x C-b in the selected window and that window
shows the buffer list already.  You might call it a feature but when
`display-buffer' is used programmatically, popping up or using another
window to show a buffer already shown elsewhere is usually considered a
nuisance.

So something better is needed here.
