Thanks Alden.  That worked.  I did a short visual search and couldn't 
find any lines that didn't have two characters, but with 76,000 lines I 
couldn't look at all.  Now all I see have only LF.

Just for my own edification, is there any way to grep for a certain 
non-printing ascii character?  The Linux programming bible says \xyy 
would find ascii yy, for instance \x07 finds the ascii bell.  But I 
wonder if maybe that only works in perl.
