ROOT prompt tab completion "leaks" private members

[jblomer]

For the following class definition

class A {
public:
   int x; 
};
class B : public A {
private:
   using A::x;
};

the tab completion of b.<tab> of an object B b; shows x. Normally, private data members are not shown though.

RInt tab completion seems to be just using the list of members returned by TClass::GetListOfAllPublicDataMembers(), which for the reproducer above includes x. 😮‍💨

How crucial is the fix of this - is there a problem (beyond tab completion) that is a consequence of this bug? This seems to be a very uncommon setup for member access; unless I get some good motivation I'm going to flag this as "low priority". Let me know!

This is low priority, but I add more eyes to it: perhaps we can have a simple idea.
