	Yes, this is the case here (sorry, I'd meant to mention
that) - we have files with LF line endings, a few wound up with
CRs in the lines due to the data involved.  Thus we've got
text files with LF line endings and a CR (one or more) in the
middle of some of the lines.

	My simple example (note the cr after the colon):

% od -a CRtoNL.txt 
0000000    T   h   i   s  sp   i   s  sp   t   h   e  sp   t   e   s   t
0000020    :  cr  sp  sp   a   n   d  sp   s   h   o   u   l   d  sp   a
0000040    l   l  sp   b   e  sp   o   n   e  sp   l   i   n   e  nl    
0000057

	Open the above with TextMate and save (no need to add another line):

% od -a CRtoNLTMSaved.txt
0000000    T   h   i   s  sp   i   s  sp   t   h   e  sp   t   e   s   t
0000020    :  nl  sp  sp   a   n   d  sp   s   h   o   u   l   d  sp   a
0000040    l   l  sp   b   e  sp   o   n   e  sp   l   i   n   e  nl    
0000057
