   9 * If you want to, you can share the DB area with any number of branches.
  10 * That has advantages: you can save space by sharing all the SHA1 objects.
  11 * On the other hand, it might just make lookup slower and messier. You
  12 * be the judge.  The default case is to have one DB per managed directory.
