[GRASS-user] v.segment - how to use orthogonal offset?

[Patton, Eric]

Here's a text file I prepared for use as stdin for v.segment:

P 1 2 100 100
P 2 2 200 100
P 3 2 300 100
P 4 2 400 100

The fourth column, according to the v.segment html page, is the orthogonal
offset from the input vector. But no matter what I make this value, the
output vector is never offset, it's always in the middle of the width of the
line. What am I doing wrong here?
