I use the following function to remove the trailing ^M from such files:
(defun xsteve-remove-control-M ()
"Remove ^M at end of line in the whole buffer."
(interactive)
(save-match-data
(save-excursion
(let ((remove-count 0))
(goto-char (point-min))
(while (re-search-forward "
$" (point-max) t)
(setq remove-count (+ remove-count 1))
(replace-match "" nil nil))
(message (format "%d ^M removed from buffer." remove-count))))))
Stefan.
