I was still struggling with trying to figure out why Cygwin/Xemacs
displays ^Ms in files on Windows. I guess I found the problem, but I'm
wondering about exactly what I'm seeing.
I noticed that I had hardcoded a setting of (for some reason lost in
antiquity):
(setq-default buffer-file-coding-system 'undecided-unix)
In my "init.el". I thought that coding systems might have something to
do with this. I tried commenting this out, and it appeared to fix the
problem. Now, when I view either Windows-created files, or Unix-created
files, they show with no ^Ms.
What's curious is, when I had this hardcoded setting, in my mode line, I
would always see "Auto---". Now that I removed the line, I see either
"Raw---" or "Raw:T-". I see the "Raw:T" on files that have
DOS eols. I
don't know what the ":T" specifically means, but it seems odd to me that
the notion of "Auto" and "Raw" seems opposite to what it appears to
be
doing. When it was showing "Auto", it felt like it was "raw",
because
it would show the file contents without parsing out the ^Ms. When it
was showing "Raw", it did parse out the ^Ms.

Hi David, I can't find the relevant docs myself now, but :t indicates
it's a Windows text (vs. binary) file (a file with CRLF line endings,
as opposed to LF only).
Hope this helps,

The best and only thing I find on eol coding is this:

That's a good guess, but happens to be wrong.
"Auto" and "Raw" refer to character coding and not to EOL processing
at all. You have forced the character coding to "autodetect", and it
stays that way because non-Mule XEmacs (ie, pre 21.5.6 on Windows) has
no detection logic. I guess we could add some code to force that to
"Raw" in no-Mule XEmacsen (because "Raw" is the only way that they
know how to process character codes), but it would be a lot of
effort for little gain.
I'll put something in the FAQ and the User's Guide.

EOL processing is indicated by the presence of :t (Mac) or :T (DOS),
or their absence (Unix).
I'll look into adding balloon help to the coding info in the modeline.

That would be much appreciated and I would apply the patches to the
stable branch.

Thanks, Stephen!
