  /* GIVEN:  A and B, with common ancestor ANCESTOR, where A and B
     directories, and E, an entry in either A, B, or ANCESTOR.

     For every E, the following cases exist:
      - E exists in neither ANCESTOR nor A.
      - E doesn't exist in ANCESTOR, and has been added to A.
      - E exists in ANCESTOR, but has been deleted from A.
      - E exists in both ANCESTOR and A ...
        - but refers to different node revisions.
        - and refers to the same node revision.

     The same set of possible relationships with ANCESTOR holds for B,
     so there are thirty-six combinations.  The matrix is symmetrical
     with A and B reversed, so we only have to describe one triangular
     half, including the diagonal --- 21 combinations.

     Our goal here is to test all the possible scenarios that can
     occur given the above boolean logic table, and to make sure that
     the results we get are as expected.  

     The test cases below have the following features:

     - They run straight through the scenarios as described in the
       `structure' document at this time.

     - In each case, a txn is begun based on some revision (ANCESTOR),
       is modified into a new tree (B), and then is attempted to be
       committed (which happens against the head of the tree, A).

     - If the commit is successful (and is *expected* to be such),
       that new revision (which exists now as a result of the
       successful commit) is thoroughly tested for accuracy of tree
       entries, and in the case of files, for their contents.  It is
       important to realize that these successful commits are
       advancing the head of the tree, and each one effective becomes
       the new `A' described in further test cases.
