So probably we should have some `quote-fold-search' with the same
toggles.  Then modes need to specify somehow which replacements are
valid, e.g., elisp-mode would define something like ((?` ?` ?‘) (?' ?'
?’)) meaning that ` matches itself and also an opening quote, and '
matches itself and also a closing quote.
