Hi,

I've already posted FASM and NASM scripts elsewhere. But since
it's still better than annoying off-topic spam, I may as well post
yet another version (A86) here.

Again, I tested with either GNU sed or Laurent Vogel's Cheap sed.

Sorry about line wrapping. Also, the second script is only because
A86 refuses to optimize forward jumps as short. Not a deal breaker,
but I still wanted to be exact.
