bug#23662: 25.0.94; isearch-toggle-character-fold keybinding missing

[dan . dever]

According to the "Lax Search" Info page, isearch-toggle-character-fold
should be bound to `M-s '', but that does not appear to be the case.
The actual bindings I see, with `M-s C-h', are these:

    Global Bindings Starting With M-s:
    key             binding
    ---             -------

    M-s ESC             Prefix Command
    M-s .               isearch-forward-symbol-at-point
    M-s _               isearch-forward-symbol
    M-s h               Prefix Command
    M-s o               occur
    M-s w               isearch-forward-word

    M-s h .             highlight-symbol-at-point
    M-s h f             hi-lock-find-patterns
    M-s h l             highlight-lines-matching-regexp
    M-s h p             highlight-phrase
    M-s h r             highlight-regexp
    M-s h u             unhighlight-regexp
    M-s h w             hi-lock-write-interactive-patterns

    M-s M-w             eww-search-words

BTW, many thanks for the character-folding search feature.  I've wanted
that for a long time.
