No. It is *DOS* (i.e. emacs) routines that add CR. Do not forget that
line separator in DOS is CR-LF. So, emacs is (most probably) simply
writes a line in text mode that results in CR-LF being actually sent
over the wire (this CR-LF<->LF translation in DOS is really weird, but
you need it to get some sort of compatibility with standard libc).
Cygwin does *not* adds anything, it reads it "as is".

Erm ... have you even tried to look at Cygwin page I told you about?

CYGWIN=nobinmode
And export it before starting shell in emacs. How exactly you do it in
emacs I do not know.
