 *
 *  The following is a bit of a kludge: because we always backup a

 *    in the backup. One is when we encounter the directory and find
 *    we cannot recurse into it, and the other is when we find an

 *    use includes the directory twice.  In this case, Verify
 *    VolumeToCatalog fails because we have two copies in the catalog,
 *    and only the first one is marked (twice).  So, when calling from Verify,
 *    VolumeToCatalog jr is not NULL and we know jr->FileIndex is the fileindex
 *    of the version of the directory/file we actually want and do
