The canonical way around this is to simply convert the
entire file to a single line ending. If you don't have
dos2unix installed, you can do it with perl:

perl -pi -e 's/\r\n/\n/g' list_of_files_to_fix

If you want to view it in emacs, you can install the
blank-mode package:

You mean you entered hexl-mode inside of emacs, right? :)
