Xdebug only shows which variables are actually *used* in a scope. If you
have a $_GET in your function it should show up in the local vars list
as well.

If you use the "global" keyword, a local reference to the global
variable is made introducing the variable as a local variable.

Yes, I guess the "Globals" should just contain the super globals then
only. I just committed a patch that should do just that.
