[R] lty dots pdf issue

I'm trying to redo an old plot with:

>  sessionInfo()
R version 2.11.0 Under development (unstable) (2010-02-09 r51113) 

When I do:

pdf("lty.pdf",height = 6, width = 8)
u <- 1:100/100
y <- matrix(rep(1:10,each = 100),100)
matplot(u,y,lwd = 2,type ="l")

the line types that have dots are difficult to distinguish because the "dots"
that should appear are rendered as very thin vertical lines and it appears
that the dashes are rendered without the lend "round" feature even though
par() reports that that is the setting.  I'm viewing all this with Acrobat 9 pro,
but my printer produces something quite consistent with what is viewable
on the screen.  

Apologies in advance if this has an obvious resolution, I didn't see anything
in the r-help archive.
