I suppose, we want it. But there are a questions/issues:
- Is it needed to introduce new function? may be it will be better to add option
to existing headline function. I'd like to keep current layout: ts_headline
provides some common interface to headline generation. Finding and marking
fragments is deal of parser's headline method and generation of exact pieces of
text is made by ts_headline.
- Covers may be overlapped. So, overlapped fragments will be looked odd.


In any case, the patch was developed for contrib version of tsearch.
