CRLF is the reason. I forgot to mention I was using CVS code that
time. I did not know that CVS client would do LF -> CRLF then
(downloaded from
http://ftp.gnu.org/non-gnu/cvs/binary/stable/x86-woe/cvs-1-11-22.zip).
I checked my system, msys cat was the only cat. It cat'ed what was
there, LF -> LF, and CRLF -> CRLF.

BTW, is it possible to keep line ending using that CVS?

Using groff-current, I finally finished making. Those problems, except
stray byte, still exist. "make clean" is done before make again.
