Either way should work.

Note that your current method has the advantage that it (presumably)
automatically works "right" when the buffer is displayed in multiple
windows (where the "reveled" part in one window isn't revealed in the
other).  Doing the same by activating/deactivating overlays is
more painful.

I'd just move its `display` property to another property and then back
(I'd keep the overlay to detect when you leave).

I see you committed something but haven't had time to look at it yet.
