Super. That's what I thought. Just was not sure if it is to code. There
must be a way to reuse all those wires in all the buildings in the world.
Problem solved.

Chris L. pointed out that it is not to code for wires smaller than

might be the way to go here anyway, and there's a good chance the
inspector would OK it.

To his summary posting, I said I'd use a GFCI in two wire mode and not
bother with trying to ground it unless I figured it was _absolutely_
necessary to have a ground. A GFCI generally protects people from shocks
better than a ground does anyway. There are times where you really do
want a ground - ie: computers.

If it was for something potentially life endangering (eg: poolside
lighting or a spa heater), I'd bite the bullet and pull new wire.
