It looks like a display bug!

I copied the two ^M^M to *scratch* and tried to investigate what was
there. I saw some strange things, but the most enlightening was when I
copied these characters as a line. With cua-mode on I selected the
line and copied it to a new location. Then suddenly it became

  ^M
                            (line 34)^M

which is actually what you can see in the file

   info/emacs-7
