^M^J, I think you mean (CRLF).

Emacs is not totally consistent about how it does this: since it tries to guess the file encoding it will usually indicate (DOS) on the mode line, but not always (and it sometimes displays the ^M's, even on Windows).

But to the point: how often do people get DOS-style files on a Unix-alike? You have to work pretty hard to do this, and there comes a point at which complicating R to workaround wrongly encoded files is not worth the trouble. Let's see if anyone else reports having done this.
