[docs] [issue17576] PyNumber_Index() is not int-subclass friendly (or operator.index() docos lie)

I'm not sure this is right solution. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue17576> _______________________________________
