Subject: Bare Control-M in files

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.
This should have gone to BUG-FILE @ MIT-OZ rather than BUG-ZWEI, since it is the Tops-20
FILE server that translates the bare CR's to M's. The reason for this is that there is
no representation in the Lisp Machine character set for bare-CR. The lack of such a
representation is deliberate; back when we designed that character set we thought it
was very important to eliminate the concept of "bare carriage returns" once and for all.
The Tops-20 FILE server used to translate bare carriage returns into the same thing
it translates CR-LF sequences into. Unfortunately, that made Zmail break when reading
a Tops-20 mail file with bare carriage returns in it. This is really not a problem with
Zmail but with the kludgey format of mail files used by Tops-20 and Tenex, so we changed
the FILE server.
