Those are mistakes--these 2 paragraphs:

    If you type @key{TAB} again immediately, it cannot determine the
  next character; it could be @samp{-}, @samp{a}, or @samp{c}.  So it
  does not add any characters; instead, @key{TAB} displays a list of all
  possible completions in another window.

    Next, type @kbd{-f}.  The minibuffer now contains @samp{auto-f}, and
  the only command name that starts with this is @code{auto-fill-mode}.
  If you now type @key{TAB}, completion fills in the rest of the
  argument @samp{auto-fill-mode} into the minibuffer.

should use @kbd{@key{TAB}} where they say "when you type".  Feel free
to fix those blunders as part of the patch.

LGTM, thanks.
