Upon any motion (other than for a judgment for money), or upon any interlocutory order or proceeding, the court may give or refuse costs, at its discretion, unless it be otherwise provided. It may, when a demurrer is sustained to a plea in abatement, give judgment for the plaintiff for his full costs to the time of sustaining it; and when any other part of the proceedings is adjudged insufficient, it may order all costs occasioned by such insufficiency to be paid by him who committed the fault.
