[igraph] igraph 0.6 output of graphs

[address@hidden]

Why did the R output of graphs change in igraph 0.6?  See below for example. I am using this with R version 2.15.

Thanks, Alan

R commands:

g <- graph(c(1,2)
g

igraph 0.6 output:

IGRAPH D--- 2 1 --

igraph 0.5.5-4 output:

Vertices: 2
Edges: 1
Directed: FALSE
Edges:
[0] 1 -> 2
