I think I understand now. This seems to imply that we have to create
point, line and polygon shapefiles from the same input file. I think
this is a bit beyond the initial scope of the plugin and will need some
rethinking. Anyway I'll try to work on it when I have some spare time.

I'm setting a launchpad project for points2one and filed this as a
feature request:
