I added this as a static method instead of just putting it in an anonymous
namespace in the cpp file because we need to be able to use the private
MarkerList and MarkerLists typedefs, which don't really seem like they should be
public (but that would be another option).

Maybe introduce |DocumentMarkerListSet| class?

+                                         DocumentMarker::MarkerType);
   bool PossiblyHasMarkers(DocumentMarker::MarkerTypes);
   void RemoveMarkersFromList(MarkerMap::iterator, DocumentMarker::MarkerTypes);
   void RemoveMarkers(TextIterator&, DocumentMarker::MarkerTypes);
