[Rd] Example in pdf() help file (PR#8083)

[Erik.Jorgensen@agrsci.dk]

The example in the help file for pdf() plots the characters outside
the plotting area in this for loop:

    for(i in c(32:255)) {
         x <- i
         y <- i
         points(x, y, pch=i)
     }

The following loop seems to be working as intended

     for(i in c(32:255)) {
         x <- (i-31)%%16
         y <- (i-31)%/%16
         points(x, y, pch=i)
     }

As an extra observation, with code page ISOLatin2, the pdf-file fails to 
open in Ghostview 4.7 using ghostscript 8.51. Error message below. In 
Acrobat Reader 7.0 it opens without problems. It is quite possible that 
it is the settings on my computer that causes the error,
but I include the dump of the error message, just in case anybody was 
interested
