When parameter force_allocation is false *and* the box set has exactly one chunk, this chunk is returned directly - w/o copying it. That mode is never used, and it's highly problematic as it's unclear whether we have to free the returnd object or it's still owned by somebody else. Just dropping the useless parameter / corner case to make the function simpler and more robust.
