Re: Any way to remove ^L or ^M from some buffer outputs?

[Patrick Mahan]

I have a user defined lisp function -

;; If you encounter a file with ^M or ... at the end of every line
;; this gets rid of them by pressing F5.
(defun cut-ctrlM ()
  "Cut all visible ^M."
  (interactive)
  (beginning-of-buffer)
  (while (search-forward "\r" nil t)
    (replace-match "" nil t))
  (not-modified)
  (beginning-of-buffer))
