Various spell bugs..

I've always noticed and accepted this, but I wonder if it would be "Fixed" as it were.. We've always accepted that when we cast certain spells (like cancellation) and there are no more spell-affects to cancel that it just returns nothing back. No linefeed, no carriage return. When you cast it again, the same happens.. I'm at work, so I cannot login to try to remember other similar spells which do that, but I know it was originally by design to have no linefeed or carriage return. But at this point, is that still the case? Thanks.
