I pasted it exactly as shown above and it worked flawlessly on my

I guess installing OpenBSD isn't the answer you're looking for... ;-)

As the other poster suggested, you can try something else. This may be

CAN be bothered to test it (and it works [again, on OpenBSD. try your
own system]):

sed '/^$/d' $1
