Really? I could have sworn they can.

Maybe we should fix this then. Because word-isearch does support
lax-whitespace AFAIR.

I tried.  Maybe I made a mistake.  Can you show an example where it
does?

Check the doc, to see what behavior to expect. ;-) (just kidding)

I wasn't sure earlier, but yes, they do.

Just type "a    b" in a buffer and do `word-search-forward' for "a b".

That's not because of lax-space matching, IIUC.  That's because word
search ignores any non-word characters between words.

What I meant is this:

  C-s M-s w a b M-s SPC

After you type the "M-s SPC" toggle, Emacs says "[match spaces
literally]", but "a   b" etc. are still highlighted as matches.

Maybe we should add a note that, although lax-whitespace matching is
not supported with word search, it is also not needed, because spaces
between words are ignored anyway?

Yes. We shouldn't say it can't do lax-whitespace, cause the reality is that
it can't NOT do lax-whitespace.

We can either say nothing, or say something like:
The word search commands don't perform character folding and are not
affected by lax whitespace matching (since they ignore the spaces between
words anyway, @pxref{Lax Search}).

I said instead that lax-whitespace matching has no effect on these
commands.

FWIW, this is a message that doesn't mean a whole lot to me. 

No idea what sounds good.  But I'm glad something does. ;-)
