On a binary mount, just running something through sed will remove \r
("^M") from the line ends without removing other occurrences of \r.
/c> echo -e '1111\r22\r' | od -c
0000000 1 1 1 1 \r 2 2 \r \n
0000011
/c> echo -e '1111\r22\r' | sed -e 's/ / /' | od -c
0000000 1 1 1 1 \r 2 2 \n
0000010
Use of the sed -i option will modify files in place.
Try it. YMMV
