[igraph] Simplify sums up weights in dev version 0.6-1899 ?

[Przemek Grabowicz]

Hi there,

In stable version of igraph these commands transform graph with multiple 
edges into weighted graph:

E(g2)$weight<-count.multiple(g2)
g2=simplify(g2)

But not in igraph_nightly_0.6-1899-20100505. It's like this because new 
simplify() apart from removing multiple edges it also sums up weights of 
those edges and put them all into the edge left.

Is it intentional or a bug? How can I create weighted graph in dev version?


Pms.
