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))))))
