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.
