[Typo in step 3: `lazy-max-at-a-time' should be
`lazy-highlight-max-at-a-time' (as in step 5).]

It would be great to hear back about this.  Is this a bug or am I
misunderstanding something?  The doc seems to say that you can expect
that all search hits will be highlighted when the value of
`lazy-highlight-max-at-a-time' is nil: "A value of nil means highlight
all matches."  Even the Customize value menu text says this.
