bug#58672: 29.0.50; [noverlay] overlays-in returns overlays for empty range

[Stefan Monnier]

> Fix was pretty simple.  We iterate with an END range of ZV or ZV+1, then

Thanks, merged.

[ I'm still trying to track down the origin of bug: the new code should
  not just reproduce the behavior of the old one, but it should also
  preserve as much of the old code as possible to avoid introducing such
  bugs.  ]
