Weaken assertion in mixed Sparse-Dense linear_combine(). (Note: they can be called in Constraint_System::affine_preimage() with a second argument row with a smaller size than the first one; see e.g. test02() in tests/Concrete_Expression/polyhedron1.cc). a call in Constraint_System::affine_preimage()).
