I think he's trying to do:

  generate_data | sed 's/[^\r]*\r//g' | tee output.txt

But I found it unclear from the description. (My own first reaction was
"dos2unix works in a pipe".) I agree it's not tee's job.

Also, the lines don't START with \r, they END with \r. Even if you're eliding
differently terminated lines you believe will be overridden, it's still a line
terminator.
