The freedom of an implementation to go either
way on that point is a good reflection of the
fact that neither way is obviously better than
the other *and* it is easy for programs to not
rely on one way or the other.

Changing the language to force one choice is
just arbitrary.  It adds an implementation burden.
It punts on the question of which choice is better.

"Unspecified" seems like the accurate spec.
