如何让Emacs打开一块代码?

(defun tcl-multiline-options ()
  "spread option/value pairs across multiple lines with continuation characters"
  (interactive)
  (save-excursion
    (tcl-join-continuations)
    (beginning-of-line)
    (while (re-search-forward " -[^ ]+ +"  (line-end-position) t)
      (goto-char (match-beginning 0))
      (insert " \\\n")
      (goto-char (+(match-end 0) 3))
      (indent-according-to-mode)
      (forward-sexp))))

(defun tcl-join-continuations ()
  "join multiple continuation lines into a single physical line"
  (interactive)
  (while (progn (end-of-line) (char-equal (char-before) ?\\))
    (forward-line 1))
  (while (save-excursion (end-of-line 0) (char-equal (char-before) ?\\))
    (end-of-line 0)
    (delete-char -1)
    (delete-char 1)
    (fixup-whitespace)))
