This is a problem on w32, but might be more general. I can not
understand how to get rid of ^M from the output of the program Tidy when
I run it with `shell-command-on-region' (or in other ways). From the
documentation it looks like `coding-system-for-read' or
`coding-system-for-write' should be used, but setting them does not
remove ^M.
I have made an example below. It uses the program Tidy from
http://tidy.sourceforge.net/trt/tidy_win32.zip. (Tidy is a program for
(X)HTML curing.)
I am doing this on w32 with GNU Emacs 22.0.50.1 (i386-mingw-nt5.0.2195)
of 2006-05-13
*** Example code:
(defvar temp-html
;; Start-here
"
<html>
<head>
</head>
</html>
") ;; Stop-here
(defun temp-c-m()
(let* ((temp-buffer (get-buffer-create "temp-c-m"))
(start (save-excursion
(goto-char (point-min))
(search-forward "Start-here")
(forward-line 2)
(point)))
(end (save-excursion
(goto-char start)
(search-forward "Stop-here")
(beginning-of-line)
(point)))
(command
(concat "c:/dl/programs/Tidy.exe"
))
(coding-system-for-read 'undecided-dos)
(coding-system-for-write 'undecided-dos)
)
(with-current-buffer temp-buffer
(erase-buffer))
(shell-command-on-region start end command temp-buffer nil)
(with-current-buffer temp-buffer
(goto-char (point-max))
(insert (current-time-string) "\n\n"))
))
(temp-c-m)

I made this HTML file (with dos coding system):
--- temp.html ---
<html>
<head>
</head>
</html>
-----------------
and run Tidy.exe as this in Cygwin terminal.
% Tidy.exe < temp.html 2>&1 | od -c
Then the output was like this:
0000000 l i n e 1 c o l u m n 1
0000020 - W a r n i n g : m i s s i
0000040 n g < ! D O C T Y P E > d e
0000060 c l a r a t i o n \r \r \n l i n e
0000100 4 c o l u m n 1 - W a
0000120 r n i n g : d i s c a r d i n
0000140 g u n e x p e c t e d < / h
0000160 t m l > \r \r \n l i n e 2 c o
As you see, the output contains \r\r\n sequence. But,
undecided-dos docodes only the \r\n sequnce into \n. That's
why you see the remaining \r.
So, it seems that it is the problem of Tidy.exe.

Thanks Handa, I did not think of that at all. It is a bit hard to
imagine how that error emerged. However there is already a bug report on
this and I hope it will be solved:
