Please use the PERLIO layers, due to problems with PERLIO and
binmode() in perl I patched perl to default to PERLIO=unix, you can
override this by setting PERLIO in your environment to PERLIO=crlf
which will push the CRLF layer on top, perl will do conversion of \n
to \r\n automatically then.

$ ./perl_newline.pl

$ od -c test.txt
0000000   F   o   o  \n   B   a   r  \n
0000010

$ export PERLIO=crlf

$ ./perl_newline.pl

$ od -c test.txt
0000000   F   o   o  \r  \n   B   a   r  \r  \n
0000012
