Modified files:
	src            : Polyhedron.cc 

Log message:
	Corrected an error in the second technique of
	Polyhedron::BBRZ02_widening_assign(): we add the system of generators
	`valid_rays' if the new ray has all homogeneous coefficients equal to zero
	or if adding only a ray there is not stabilization.
