The test in NetCheck does seem not fully correct.

I think it is always true that:
- the last point of the last line in a NET entry never has the
   node-flag set.

The test in NetCheck is circular because it does not know if the last
point in a line is really a 'node'.  So it doesn't properly test the
condition 'if the point is a node'.

Maybe the test is worthless. I will change it so that we only test
the last line.
