[ROOT] Updating gDirectory when Friend trees are added

Hello (my day for ROOT emails)

I've noticed working with the TTree member function AddFriend() that the 
following code

TTree *t=new TTree();
t->AddFriend("tother","toto.root");
t->SetName("toto")

does not produce a corresponding entry in gDirectory. I cannot retrieve the 
tree using the
usual (TTree*)gDirectory->GetList()->FindObject("toto") approach, this 
although the tree now (theoretically) associated with tree "tother".

Shouldn't an entry to gDirectory be added when this happens ?

Regards

Malcolm
