#2488: v.neighbors: "No points found" error while using points map

     Type:  defect       |      Status:  new                      
 Priority:  critical     |   Milestone:  7.0.0                    
Component:  Vector       |     Version:  svn-releasebranch70      
 Keywords:  v.neighbors  |    Platform:  Linux                    
      Cpu:  Unspecified  |  
-------------------------+--------------------------------------------------
 The functionality of v.neighbors is a bit obscure to me:

 {{{

 Is the module not working or is the use case wrong?
