如何在emacs术语中禁用自动线切割？

我正在使用emacs终端模拟器。GNU Emacs 23.2.1和GNU bash，版本3.00.0（1）-发布。 当一些命令（比如grep1 file.txt）打印很长的行时，emacs会将其主干化以适应窗口宽度。 但它是这样做的，当我复制这样的线条时，我得到的不是一条长线条，而是几条宽度相等的线条

例如：

    Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. 

重复后，用

cat lorem.ipsum

我得到（如果我有一个38字符宽的终端）：

现在，如果我从终端复制它，我将有4行用\n个字符分隔。

这很烦人，怎么处理呢？

事实上，我没有找到答案，但我已经编写了一个快速的方法，可以轻松地将这些剪切粘贴到术语中：

;; Linearize the last kill-ring entry
(defun make-single-line-in-clipboard ()
  (interactive)
  (with-temp-buffer
    (yank)
    (pop kill-ring)
    (goto-char 0)
    (while (search-forward "\n" nil t)
      (replace-match "" nil t))
    (kill-region (point-min) (point-max))))

;; Paste into terminal the linearized last killed text
(defun paste-into-term-singlelined ()
  (interactive)
  (term-line-mode)
  (make-single-line-in-clipboard)
  (end-of-buffer)
  (clipboard-yank)
  (term-char-mode))

然后，对C-y的bing（我使用扩展名）

;; Linearize the last kill-ring entry
(defun make-single-line-in-clipboard ()
  (interactive)
  (with-temp-buffer
    (yank)
    (pop kill-ring)
    (goto-char 0)
    (while (search-forward "\n" nil t)
      (replace-match "" nil t))
    (kill-region (point-min) (point-max))))

;; Paste into terminal the linearized last killed text
(defun paste-into-term-singlelined ()
  (interactive)
  (term-line-mode)
  (make-single-line-in-clipboard)
  (end-of-buffer)
  (clipboard-yank)
  (term-char-mode))

 (cons "C-y" 'paste-into-term-singlelined)
