You're on some form of linux/unix I take it? My first suggestion  
would be to make a copy of the file, then in emacs do a global  
replace of ^M with return (which shows up as ^J). It's been a long  
time since I've done this, but there's a way. Invoke "query-replace",  
then type "ctrl-q ctrl-m ctrl-j" (no quotes and holding down the ctrl  
key) to tell emacs to search for ^M, then type "ctrl-q ctrl-j ctrl-j"  
to replace all the ^M characters with line returns.
