Comment (by hcho):
Yes, that's what I found too. Vect_line_intersection2 doesn't have this
issue, but it still creates a single point intersection at the first
vertex of the second new line (line ID 3) in the geojson example.
Line ID 1: original unbroken line
1st iteration
Line ID 2-4: new broken lines
2nd iteration
Line ID 5: identical to line 3
Line ID 6: start node of line 3
Lines 5 & 6 shouldn't be returned at all from the intersection routine, I
think. The patch fixes this.
