备注
Completely revised version. Lemma 2.10 has been corrected. The flow of the main argument has been remarkably simplified, Proposition 2.16 and Lemma 3.5 have been strengthened accordingly. The final part of the previous version concerning Gaussian maps on general curves has been split off and will be the object of a forthcoming paper
