Summary: Trivial improvement to NameError message

Initial Comment:
This is a trivial change, but since code may depend on the
exact wording, I'm submitting a patch for review.

The compiler knows when there's no locally bound name
and generates LOAD_GLOBAL.  If a NameError is raised
during that instruction, it generates an error message like

    global name 'XYZ' is not defined

This can be misleading to new users.  The fact that the
name is not found by LOAD_GLOBAL is strictly an
optimization detail.  I think something like the attached
patch would be better.
