Oh, I see.  I was considering that since the meaning of \’bar hasn't
changed, then escaping hasn't changed (though non-escaped syntax has).

Anyway, thinking about this made realize I broke read->print
round-tripping for these symbols, because I didn't change print to add
the backslash.  Attached is a patch which does this, but I'm not sure if
it can go into emacs-26.  If not, then I think we should at least delay
introduction of the reader change to Emacs 27.
