Pushing new branches does not set up tracking branch completely

When you push a local branch that does not exist on the remote (using the refspec overload), libgit2sharp automatically creates a tracking branch, but it does not set up the config for the local branch

i.e. the following config entries are missing:

branch.(branch_name).remote
branch.(branch_name).merge

Currently, I push a new branch like as follows:

string refspec = string.Format("{0}:{1}",
    currentBranch.CanonicalName, currentBranch.CanonicalName);
repo.Network.Push(remote, refspec, handler, credentials);
repo.Branches.Update(repo.Head, delegate(BranchUpdater updater)
{
    updater.Remote = remote.Name;
    updater.UpstreamBranch = repo.Head.CanonicalName;
});

I feel like this should be simplified. Either by doing the BranchUpdater stuff in Push(), or by extending the Push(Branch, ...) overload to let it accept non-tracking branches and do the whole process.

I also did not find a test fixture covering that feature, so the intended behaviour should at least be specified.

Start by reading the Push overloads and the BranchUpdater usage shown in the issue, then inspect existing push test fixtures because the issue says none cover this behavior. Done means the supported new-branch push path establishes the branch.remote and branch.merge configuration, with a test specifying the intended behavior.
