I think that's too narrow to be really useful as a dedicated feature
for authors (although maybe UAs will want to use it in their default
stylesheets).  The number of authors who want to highlight the
matching suggestion but don't want any further markup seems like it
would be too small to justify a special-case feature.  Especially
since if you get even slightly sophisticated, you might be returning
results that don't have the given string as an exact substring, e.g.,
if you normalize spacing and punctuation before doing matches (let
alone doing typo fixes and synonym substitutions like Google).

That does seem like a very logical way to do this.  It would be cool
if this were possible -- it's a pain to get the absolute positioning
and such right as it stands.
