Re: The window-pub branch

I found out that hooking ediff to use just 'display-buffer is
actually easy via 'ediff-window-setup-function'.

Here is some code if you want to test your future version of
'display-buffer'.  It works quite well with a slightly improved
version of EWM for 'ediff-files'.

The wrapper calls two functions that you'd need to have:

     my-display-multi-buffers (list-of-buffers-and-labels)
     ;; display some buffers and return list of their windows

     my-select-window (window)
     ;; select 'window' and frame where it's on:

The stuff in the apply form is from ediff-setup-windows-plain-compare.
Don't ask me what it does.

(setq ediff-window-setup-function
       (lambda (A B C H) ;; buffers
         (apply (lambda (WA WB WC WH) ;; windows
                  (ediff-with-current-buffer control-buffer
                    (setq ediff-window-A WA
                          ediff-window-B WB
                          ediff-window-C WC
                          )
                    (when ediff-windows-job
                      (set-window-start WA
                        (ediff-overlay-start
                          (ediff-get-value-according-to-buffer-type
                            'A ediff-narrow-bounds)))
                      (set-window-start WB
                        (ediff-overlay-start
                          (ediff-get-value-according-to-buffer-type
                            'B ediff-narrow-bounds)))
                      ))
                  (my-select-window WH)
                  (ediff-setup-control-buffer control-buffer)
                  )
                (my-display-multi-buffers
                 `((,A . ediff-A)
                   (,B . ediff-B)
                   (,C . ediff-C)
                   (,H . ediff-H)
                   ))
                )))
