Oh, I see. I should have read that node in the manual. :-)
Anyway, I've grepped through the Emacs tree, and I can't find any places
where we're binding/setting `selective-display' to t, so there indeed
doesn't seem to be any usages of the obsolete form.

Right. So if we don't want to obsolete the other form (and Eli says he
uses it all the time, so it doesn't sound like we want to), then I guess
there's nothing more to be done here? So I'm closing this bug report.
