I think I got it - please confirm my understanding. When I open the file in vi I only see 1 ^M. In ultraedit I see what looks like 2 carriage returns 0D 0D.

tr -d '\015' < filename > o.txt

the above removed the extra carriage return. Then I tried it on the output file and it left the file unchanged.
