hmm maybe I do not understand, but there  is no parameter curves inside 
the parameter asignment
    params <- i.parse.plot.params(graph, list(...))
    vertex.size <- 1/200 * params("vertex", "size")
   ..    frame <- params("plot", "frame")
plot() is only called if !add I think this means only the first time
igraph.Arrows is used to draw the arrows and there I do not find any 
assignment for curved.

?igraph.plotting redirects me to plot.common.html
and there is no word inside beginning with curv...
I also did a complete text search, (before I asked you again) in all files of the R-directory
I found it only in the library diagram and network 

network.arrow(1,1,2,2,curve=0.1,width=0.01,col="red",border="black") # this is working fine
or for curved arrowheads.
