print f()
print x

This kind of code didn't work correctly because x was treated as free
in i, leading to an attempt to load x in g to make a closure for i.

Solution is to make global decl apply to nested scopes unless their is
an assignment.  Thus, x in h is global.

described in PEP 227.

symtable_check_unoptimized() warns about import * and exec with "in"
when it is used in a function that contains a nested function with
free variables.  Warnings are issued unless nested scopes are in
effect, in which case these are SyntaxErrors.

symtable_check_shadow() warns about assignments in a function scope
that shadow free variables defined in a nested scope.  This will
always generate a warning -- and will behave differently with nested
scopes than without.

Restore full checking for free vars in children, even when nested
scopes are not enabled.  This is needed to support warnings for
shadowing.

Jeremy, just follow the example of the call to PyErr_WarnExplicit()
that I *did* include.
