How do I remove edge lines?

[James Curry]

I have some 100K dlg files that I have imported with v.import.
When I plot them with d.vect I notice that there are lines at the
edges of each quad. I'd like to remove these lines. 

I have tried v.rmedge, but it removes the information inside the quad as 
well. I tried v.digit and could not select the edge lines.

How do I import these files so that when I patch them together the
edge lines will not be visible?
