It wasn't clear to me that you wanted to just discard the `\r`s, that 
makes things even simpler. Given that - yes, you can use a separate call 
to awk to remove `\r`s before piping to your real script or you can do 
what I suggested below but change `$0 ~ /^\r?$/` to `{ sub(/\r$/,"") } 
$0 == ""`.
