Bare Control-M in files

[<Henry@APIARY-6>]

In Symbolics 3600 Release 6.0, IP-TCP 29.0, AISite 9.1,
microcode TMC5-MIC 319, FEP 17, on Lisp Machine Bing Crosby:

If you Control-X-Control-F a file which has bare Control-M [carriage returns] characters
on a Tops-20 host, Zwei seems to put M's in the file instead. Tops-20 Emacs seems
to do the right thing with these.

Example: Oz:<Henry>Raw-Control-M.Text
