As I pointed out before, the fragments *don't* necessarily satisfy
the query, so this is still promising too much.

An important edge case to keep in mind is that the given text
itself might not satisfy the query; ts_headline has no control
over what you hand it.  But even if the text as a whole does,
there may not be small fragments that do.
