bug in diff-mode.el?

[Martin Stone Davis]

The following code looks wrong to me:

(defun diff-after-change-function (beg end len)
  "Remember to fixup the hunk header.
See `after-change-functions' for the meaning of BEG, END and LEN."
...
  (when (and (not undo-in-progress) (not inhibit-read-only))
    (if diff-unhandled-changes
        (setq diff-unhandled-changes
              (cons (min beg (car diff-unhandled-changes))
                    (max beg (cdr diff-unhandled-changes))))
                ---------^^^
      (setq diff-unhandled-changes (cons beg end)))))


Shouldn't it be: (max end (cdr diff-unhandled-changes)) ?

This is version 21.3.1.
