[igraph] Problem again

[Moses Boudourides]

Hi,

Let me first describe what I'm trying to plot. It is a graph, some of
its edges being multiple, actually in more than three copies.
Something like this:

g <- graph( c( 0,1, 0,1, 0,1, 0,2, 0,2, 0,2, 1,2, 1,2), directed=FALSE )

Now the first edges 0,1 and 0,2 I want them non-curved and gray, while
all the other edges curved and colored differently (say 0,1, 0,2, 1,2
blue and 0,1, 0,2, 1,2 green).

What confuses me is that the first time 1,2 appears, I wanted to be
curved, while not for the first time of the others.

Can this be done?
