Wow Martijn. Thank you SO much. It seems to have worked. This will get a lot of use, I think. You really should get it into PostGIS as a function, for better visibility and for the benefit of the world.
I can’t wait to try it on one of my larger problems (e.g. a cadastral data set with about 2 million parcels).
