No observed bug, only theoretical ones (AFAIK, never even a ginned-up
synthetic test case has been demonstrated). Certainly not a regression,
since it has been this (wrong) way since the dawn of time. I don't think
this first change is dangerous for -stable, but I have seen no positive
rationale for pushing it there.
