Eh, sorry, you are right. reveal-mode takes care of this. I thought I
had it on, but for some reason I had commented it out.

I think I got confused by the similar mechanism in isearch that is on
by default. That it is on by default seems good. What is the reason
reveal-mode is not on by default? (I have a feeling there was some
small problem, but I can't remember now.)
