Either way is fine.
My way solves the original problem and defines methoddescriptor
as a non-data descriptor that isn't super. I think that matches what 
people expect when calling that inspect.ismethoddescriptor().
OTOH, if methoddescriptor is viewed as synonymous with
non-data descriptor, then, technically a super object should
return True and your fix will have to go inspect.isroutine().
Name your poison. Add a test case. Then fix it.
