I've reworked your patch a bit (avoiding terms like "close" and
"overlay") and applied it to Emacs 28.

Stefan was concerned that having just a defcustom wouldn't be enough
here -- that auto-reveal should/could be done via a command.  That's a
good point, but I think it's quite likely that people that prefer to
have this off will set the variable from a mode hook or something, so I
think the variable itself is useful.
