-------------------------+--------------------------------------------------
 When v.out.ogr exports a feature consisting of a single geometry and
 multiple CATs in a single layer (such thing is legal in GRASS) to format
 that doesn't support such feature (ESRI Shapefile), feature geometries are
 duplicated to create "single feature = single CAT + attributes". Such
 action preserves all data but introduces duplicated geometries in output
 data set. In such case v.out.ogr should print a warning about duplicating
 geometry in output data set as it might break v.clean rmdupl results and
 produce unexpected output.
