Nice work.  Most times I review changes to AutocompleteMatch, this block of code
gets overlooked. :-)

   associated_keyword.reset(match.associated_keyword.get() ?
       new AutocompleteMatch(*match.associated_keyword) : NULL);
   keyword = match.keyword;
   from_previous = match.from_previous;
   search_terms_args.reset(match.search_terms_args.get() ?
       new TemplateURLRef::SearchTermsArgs(*match.search_terms_args) : NULL);
   additional_info = match.additional_info;
   duplicate_matches = match.duplicate_matches;
   return *this;
 }
