Re: [PATCH] Fix display-buffer-use-some-window to honor reusable-frames

[martin rudalics]

This

+  (let* ((reusable-frames (cdr (assq 'reusable-frames alist)))
+         (frame (or (window--frame-usable-p (selected-frame))
+                    (window--frame-usable-p (last-nonminibuffer-frame))))
+         (window (or (get-lru-window (or reusable-frames frame) nil t))))

is probably not what you really want.  AFAICT you want to reuse a window
on a frame specified by 'reusable-frames' - that is a window that
already shows BUFFER.  But 'get-lru-window' only gives you the least
recently used window of such a frame.

What speaks against

(defun display-buffer-use-least-recent-window (buffer alist)
  "..."
  (let* ((alist (cons (cons 'inhibit-same-window t) alist))
         (window
          (or (display-buffer-reuse-window buffer alist)
              (display-buffer-use-some-window buffer alist)
              (display-buffer-pop-up-window buffer alist))))
    (when window
      (window-bump-use-time window)
      window)))

or something the like?
