+        You want to modify a buffer whose disk file has changed
+        since you last read it in or saved it with this buffer.

+        If you say r to revert, the contents of the buffer are refreshed
+        from the file on disk.
+        If you say n, the change you started to make will be aborted.
+

+        file, then make the change again.
