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