在emacs中如何将窗口的垂直分割改为水平分割

emacs没有原生支持，所以抄了一个函数，如下：

;;; https://www.emacswiki.org/emacs/ToggleWindowSplit
(defun toggle-window-split ()
  (interactive)
  (if (= (count-windows) 2)
      (let* ((this-win-buffer (window-buffer))
             (next-win-buffer (window-buffer (next-window)))
             (this-win-edges (window-edges (selected-window)))
             (next-win-edges (window-edges (next-window)))
             (this-win-2nd (not (and (<= (car this-win-edges)
                                         (car next-win-edges))
                                     (<= (cadr this-win-edges)
                                         (cadr next-win-edges)))))
             (splitter
              (if (= (car this-win-edges)
                     (car (window-edges (next-window))))
                  'split-window-horizontally
                'split-window-vertically)))
        (delete-other-windows)
        (let ((first-win (other-window 1)))
          (funcall splitter)
          (if this-win-2nd
              (other-window 1))
          (set-window-buffer (selected-window) this-win-buffer)
          (set-window-buffer (next-window) next-win-buffer)
          (if this-win-2nd
              (other-window 1))))))

另emacs如何将两个窗口的内容交换？调用M-x window-swap-states即可。
