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?
