   yet exist, and the REPOS_NODE_STATUS indicates that this is an addition,
   create a new status struct using the hash's pool.

   If IS_DIR_BATON is true, THIS_DIR_BATON is a *dir_baton cotaining the out
   of date (ood) information we want to set in BATON.  This is necessary
   because this function tweaks the status of out-of-date directories
   (BATON == THIS_DIR_BATON) and out-of-date directories' parents
   (BATON == THIS_DIR_BATON->parent_baton).  In the latter case THIS_DIR_BATON
   contains the ood info we want to bubble up to ancestor directories so these
   accurately reflect the fact they have an ood descendant.

   Merge REPOS_NODE_STATUS, REPOS_TEXT_STATUS and REPOS_PROP_STATUS into the
   status structure's "network" fields.

   Iff IS_DIR_BATON is true, DELETED_REV is used as follows, otherwise it
   is ignored:

       If REPOS_NODE_STATUS is svn_wc_status_deleted then DELETED_REV is
       optionally the revision path was deleted, in all other cases it must
       be set to SVN_INVALID_REVNUM.  If DELETED_REV is not
       SVN_INVALID_REVNUM and REPOS_TEXT_STATUS is svn_wc_status_deleted,
       then use DELETED_REV to set PATH's ood_last_cmt_rev field in BATON.
       If DELETED_REV is SVN_INVALID_REVNUM and REPOS_NODE_STATUS is
       svn_wc_status_deleted, set PATH's ood_last_cmt_rev to its parent's
       ood_last_cmt_rev value - see comment below.
