#3376: make remove_repeated_points leave inputs alone
---------------------+---------------------------
 Reporter:  pramsey  |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  medium   |  Milestone:  PostGIS 2.3.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 The remove_repeated_points code already mostly clones new objects, in all
 cases where it's (maybe) going to remove points. The only things that
 avoid cloning are objects (points, circular strings) that aren't going to
 be processed at all. Like most of our other functions, we should buckle
 down and make the input arguments const. (Would have avoided #3375)
