Comment:
JTS does this too. Philosophically you can swing either way. Taken in
isolation, returning a point makes perfect sense. But if I union a
collection of linestrings, I probably want the not-a-line entries to just
disappear (think, zero-length lines at the nodes of other real lines). I'm
going to 'wontfix' this as it is long-standing behaviour and not obviously
wrong, nor different from our reference base (JTS).
