That's great.

But I see that the bug demonstrated by the attached script is still present.
I have reverted in CVS the patch that I suspect is responsible.

Bastian Maerkisch is looking into the problem, but until we have a more solid
fix I think reversion is best.

Petr:
Could you test whether the latest CVS (just changed a few minutes ago) fixes
the win terminal bug as tested by the attached script?

Bastian:
The original patch that I have reverted looks wrong to me, now that I have
stared at the code.  Do you have a script that demonstrates the problem it
was originally intended to fix?  So far as I can see, there should be no
path through the code that produces a "polyline of length 1".  The vertex
counter starts at 1, and each polyline vector call increases it.  So 
(polyi == 1) really means a polyline of length 0, and we shouldn't draw it.
But maybe it should execute a MoveTo()?
