;;; Commentary:

;; Here are some functions and commands related to the *scratch*
;; buffer.

;;; Code:

;;;###autoload
(defun oni:raise-scratch (&optional mode)
  "Show the *scratch* buffer.
If called with a universal argument, ask the user which mode to
use.  If MODE is not nil, open a new buffer with the name
*MODE-scratch* and load MODE as its major mode."
  (interactive (list (if current-prefix-arg
                         (read-string "Mode: ")
                       nil)))
  (let* ((bname (if mode
                    (concat "*" mode "-scratch*")
                  "*scratch*"))
         (buffer (get-buffer bname))
         (mode-sym (intern (concat mode "-mode"))))

    (unless buffer
      (setq buffer (generate-new-buffer bname))
      (with-current-buffer buffer
