 Snapping works fine on existing lines, still for some reason fails to snap
 to line itself. I.e. try to create closed boundary consisting only from
 two verticles and one node (a triangle). v.digit fails to snap endpoint to
 startpoint. Creating a triangle from two or three lines works just fine.
 (This is note to myself: line.c *_line_update() button3 case needs to
 check also unwritten nodes for proximity)

 PS. Does it make sense for v.digit to ask for attribute data for boundary?
