Comment(by nicklas):
I think you have a typo in r8107.
pa->npoints is 1-based, not 0-based, right?
Then shouldn't it be instead?:
{{{
if ( t >= pa->npoints &&
( proj.x == end.x) && (proj.y == end.y) )
}}}
That would explain it since the answer from st_closestpoint is the same as
the second last vertex, not the last.
