[Rd] OS X PDF bug (PR#13943)

[paul.m.mcguire.jr at att.net]

par(mfrow=c(2,2))
y<-1:20
plot(y,  pch="+")
plot(y,  pch="+")
plot(y,  pch="+")
plot(y,  pch="+")

produces a pdf that is viewable in Preview (copied from the  
clipboard) but fails to print.

pch default or ="." or =3 prints.

Unfortunately pch=3 doesn't fix the mfrow=c(5,6) graph that I'm  
actually trying to print,
so the bug lies somewhere deeper.

OS X 10.4.11
R 2.9.2 GUI 1.29 Tiger build 32-bit (5464)
Laserjet 5MP
