[GRASS-user] v.in.ascii and overlapping areas

I'm confused about how grass decides what is an area with a centroid,
and what is a boundary with a point inside it. I am using v.in.ascii
to import a text file in standard mode. The file contains two
circles (boundaries) and two points (their centroids). The circle
boundaries overlap. I have notices that if the circles are close
together, so that the center point of one is with the boundary of the
other, I end up with one circle that is an area with a centroid, and
a non-area boundary and a point. If the circles are a little
further apart, I get two areas and their corresponding centroids.
I need both circles and their center points to import as areas with
centroids, no matter how close together they are.
Can anyone explain what's going on here?
