Yuck, the old behavior looked right but was subtly wrong (the
highlighting at step 5 was done via font-lock whereas it was done with
overlays at step 3), and the recent change made the difference "more
visible" ;-)
The real problem is in font-lock, I think, but I don't have the courage
to fix it now, so I've installed a workaround that I hope will be sufficient.
