For numeric constants we only need to add, since the parser doesn't produce negative numbers. For strings we only add (we actually could substract 1 if given string is a constant and it has '-number' form but we're not doing that because * we set max_length bigger then necessary in other cases as well. * the current solution is simpler and safer (bigger max_length is better then cutting out)
