I think we can use |bool| parameter for |setActiveMatch()|, because |bool|
parameter implies active or inactive.
Better name of this function is |setIsActiveMatch()|, and we can do in another
patch.

-  void setActiveMatch(bool);
+  void setActiveMatch(MatchStatus);
   void clearDetails() { m_details.clear(); }
 
   // Offset modifications are done by DocumentMarkerController.
