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
