Corrected behavior of "load ... -dereference" to bring back a

previous behavior that had inadvertently been changed.  In recent
versions, "load <absolute_path> -dereference" would incorrectly
apply the dereferencing to <absolute_path> rather than just its
subcells.  Cleaned up the code around DBCellRead() in the process,
so everything is more straightforward (although probably more
could be done in that regard).
