From Gerri:

Writing the notes I realized that the attach functionality of gROOT->Proof(...)
could be automatized, such that it attaches to the first session on the master,
if any:

   gROOT->Proof("masterhost")     // attach to first session, if any, or create one

   gROOT->Proof("masterhost/?N")     // force creation of new session

   gROOT->Proof("masterhost/?2")     // attach to session 2

In the standard case in which there is only a session this gives a very convenient
way of reconnecting.

I have fixed also a small problem with setting of fUser and fRemoteProtocol
for the second slave on a node.
