I basically just slightly modified the code in ediff-setup-windows-plain-merge from ediff-wind.el. Not too sure how to paste code on HN, here's the modified version which works for me. The orginal ediff-setup-windows-plain-merge may depend on your Emacs version though, so buyer beware (things may have changed and need to be revisited). Instead of showing: A B C D Ediff control panel I show: A B C D Ediff control panel As for Git AFAICT all I have is git config --global merge.conflictStyle diff3. Compare it to your version of ediff-setup-windows-plain-merge to see what I changed: (defun ediff-setup-windows-plain-merge (buf-A buf-B buf-C control-buffer) ;; skip dedicated and unsplittable frames (ediff-destroy-control-frame control-buffer) (let ((window-min-height 1) (with-Ancestor-p (with-current-buffer control-buffer ediff-merge-with-ancestor-job)) split-window-function merge-window-share merge-window-lines (buf-Ancestor (with-current-buffer control-buffer ediff-ancestor-buffer)) wind-A wind-B wind-C wind-Ancestor) (with-current-buffer control-buffer (setq merge-window-share ediff-merge-window-share ;; this lets us have local versions of ediff-split-window-function split-window-function ediff-split-window-function)) (delete-other-windows) (set-window-dedicated-p (selected-window) nil) (split-window-vertically) (ediff-select-lowest-window) (ediff-setup-control-buffer control-buffer) ;; go to the upper window and split it betw A, B, and possibly C (other-window 1) (setq merge-window-lines (max 2 (round (* (window-height) merge-window-share)))) (switch-to-buffer buf-A) (setq wind-A (selected-window)) (split-window-vertically (max 2 (- (window-height) merge-window-lines))) (if (eq (selected-window) wind-A) (other-window 1)) (setq wind-C (selected-window)) (switch-to-buffer buf-C) (select-window wind-A) (funcall split-window-function) (if (eq (selected-window) wind-A) (other-window 1)) (switch-to-buffer buf-B) (setq wind-B (selected-window)) (when (and ediff-show-ancestor with-Ancestor-p) (select-window wind-B) (split-window-horizontally) (when (eq (selected-window) wind-B) (other-window 1)) (switch-to-buffer buf-Ancestor) (setq wind-Ancestor (selected-window))) (balance-windows-area) (with-current-buffer control-buffer (setq ediff-window-A wind-A ediff-window-B wind-B ediff-window-C wind-C ediff-window-Ancestor wind-Ancestor)) (ediff-select-lowest-window) (minimize-window) (ediff-setup-control-buffer control-buffer) ))
