#1775: Asymmetric undetected edge motion collision

 Reporter:  strk      |       Owner:  strk         
     Type:  defect    |      Status:  new          
 Priority:  high      |   Milestone:  PostGIS 2.0.1
Component:  topology  |     Version:  2.0.x        
 Keywords:            |  
----------------------+-----------------------------------------------------
 While playing with topology edge simplification I encountered a case in
 which ST_ChangeEdgeGeom allows to change an edge geometry from A to B but
 doesn't allow it to move back from B to A.

 Looking at the movement visually I can see that the movement should never
 be allowed.
