These functions are doing weird things like: * Treating negative offsets as flagging an invalid state even though offsets can validly be negative. * Letting control flow through in some cases without an obvious initialization to zero, but then insisting on setting things to zero in other cases... like either we're starting at zero and don't need to set it, or we need to set things to zero, pick one.
