One of us (A.A. Aligia) wants to thank Sandro Sorella for discussions held at the Miniworkshop on Strong Electron Correlations at ICTP; Trieste; Italy; (July; 1996); and bringing Ref. [22] to our attention. One of us (E.R. Gagliano) is supported by CONICET; Argentina. A.A. Aligia is partially supported by CONICET;
