[Rd] legend() in a multiple figure environment

[Simone Giannerini]

Now I got how to reproduce it, it has nothing to do with multiple
figure environment but rather with figure resizing. Here it is:

 curve(dnorm,col=4,from=-4,to=4);
 legend(-4,0.3,legend="curve",lty=1,col=4)

# Now expand the figure to full screen

legend(-4,0.2,legend="curve",lty=1,col=4)
