gEDA: gschem net drawing changes

[Werner Hoch <werner.ho@xxxxxx>]

Hi all,

some time ago David Carr posted code to draw two net segments at once.

This was my reply to it:

I still have it in my local CVS tree. It work good, but it sometimes it 
produces nets with zero length in the file.
gschem tells: Found a zero length net [ N 53100 54000 53100 54000 4 ]

I'd like to track that down and apply the patch.

And now the question: 
I don't have an unpatched version of gschem at the moment.
Can someone draw a single net and tell me, whether the temporary line is 
drawn continiously or whether it jumps from gridpoint to gridpoint?

regards
Werner
