I just created the stable-4.0 branches in the jgit and egit repositories
in order to tag the 4.0.0-m1 milestone without disturbing ongoing work
For now don't push changes to the stable-4.0 branch but continue to use
the master branch for 4.0 development. We will move 4.0 development to
the stable-4.0 branch when we send the IP logs for review, this is going to
happen end of May.
