Why this doesn't just work and if not why is barework branch made then,
why at all ?
I would like to attach an existing dir to git (make it a workdir) and
then update the index with git reset and checkin the differences.
I can do that tricking around with a little dir renaming, new empty dir,
move the .git file and rename back...
