Fix Chrome-specific closure pass for cr.exportPath()

Fix Chrome-specific closure pass for cr.exportPath()

It thought cr.exportPath() should only take 1 argument
and that this one argument should only be a 'string literal'.

That's just wrong.  It was never right.  exportPath() takes
up to 3 parameters, 2 of them optional (just uncommon).

This is blocking folks that want to compile code that uses
cr.exportPath() to extend an object other than window or
pass a path that's a variable and not a 'string literal'.

Fix it how? What is broken about it? When did it break?
