OK... these are the choices then AFAICS:

(1) Put in directly on /boost

(2) Put in a new directory /boost/optional even if it will contain only this
file

(3) Put in /boost/optional, move "optional.hpp" here, and retain a root
"optional.hpp" stub for backward compatibility.

I'll go for (1) since it is possible, if not likely, that variant<> uses
"none.hpp" too.

Opinions?
