TTree::SetEstimate extension proposal

ROOT
1

I’d like to propose the following change.
Instead of:

if (n <= 0) { n = 10000; }
put:

if (n == 0) { n = 10000; } else if (n < 0) { n = fEntries - n; // n = fEntries + llabs(n); }
Then calling “MyTree->SetEstimate(-1);” would simply mean “MyTree->SetEstimate(MyTree->GetEntries() + 1);”, which is a typical case (at least for me).

Hi Pepe,
