Then why are you saying that Emacs hides CR characters from you?  It
does show them as those ^Ms.

In general, when a  file has mixed EOLs,
what will show in the mode line and what in the buffer is determined
by sheer luck, because Emacs examines only a small portion of the file
to determine the EOL format, and depending on where you have CRLF and
where just LF you can end up with either "DOS" or ^M characters.
