That's 100% wrong.  Especially in the Emacs
and Elisp manuals.  Same thing for `.  Same
thing for _any_ char, no matter how common.

We don't need a minor mode for this.  This is
about Isearch.  We need a toggle key for it.

On the other hand, we could consider whether
the same choice/decision to fold should/could
affect both Isearch and other things, such as
query-replace.
