#3279: ST_OffsetCurve return wrong result
----------------------------+---------------------------
 Reporter:  MaxS            |      Owner:  pramsey
     Type:  defect          |     Status:  new
 Priority:  low             |  Milestone:  PostGIS 2.1.9
Component:  postgis         |    Version:  2.1.x
 Keywords:  st_offsetcurve  |
----------------------------+---------------------------
 Using st_offsetcurve with specific geometry returns wrong result. It
 should be single linestring, but returns multilinestring. Geometry valid
 without repeated points. Tested on 2.1.8 and 2.1.3
