Yes, that is frustrating. If you are just working with master/origin, I
think you can get away with it due to the default configuration created,
but otherwise I'm not sure it's avoidable. I seem to recall a thread
about this a few months ago (between me and Bill Lear, maybe?), but I
don't recall that there was any especially good conclusion.

This will seem like repetition, but it's like this:

  git-clone <repo> mydir
  cd mydir
  git-checkout --track -b v1.9-clientname origin/v1.9-maint
  git-push origin v1.9-clientname    # to create the new head remotely

When you do a git-pull without arguments from the v1.9-clientname
branch, it will first do a fetch of origin (grabbing the entire state,
including the v1.9-maint branch) and then merge in origin's v1.9-maint.

When you do a push without arguments, it will push every head you have
in common with origin. Because we pushed the v1.9-clientname branch
once, it was created and will be part of subsequent pushes.
