> Highlighter.mergeContiguousFragments merges adjacent fragments it is given.  But it is
given a list of fragments that do not necessarily have embedded highlights (e.g. have a score
of 0), and so it could grow a fragment needlessly.  I never figured out why this old highlighter
keeps around such fragments instead of eagerly tossing them when the fragment completes, which
is what I think it should do.  That would address this problem and might make things faster.
 I'm not sure if any highlighter user wants the non-scoring fragments though.
