  The revision may be correct and the problem may be in the sprout.
  But do you mean, that maybe WorkingTree.commit() or Commit.commit() should do the right decoding? Maybe that's the place to investigate.

  I did originally write the test with self.run_bzr("branch ...") and found that it failed with WorkingTreeFormat4, 3 and 2. When I rewrote it with set_parent_trees, I found that only WorkingTreeFormat4 failed. So Aaron Bentley suggested here [1] to test also sprout() since that is what „branch“ uses.

  Other than:
- breaking the long line
- telling other test's path in a comment
- explaining in the comment why are there two tests
  ...should I change something else? I'll send the patch when we decide if we need both tests or not.
