(PR#4307) Re: [Rd] par(new=T) works differently in pdf vs postscript if applied before a plot statement. (PR#4037)

Please give us an example of what you mean (as the FAQ asks).  Exactly
what order are you doing things in?

You can't send scripts to graphics devices, and you should not be calling
par(new=TRUE) without a plot already done.  So it would appear to be user
error, and it may well just be different error handling in the two
devices.  If I have guessedanything like right ....

If I place par(new=T) before I create a plot in a script that is sent to a pdf 
device, the pdf is unopenable and reports itself as having no pages.  The 
postscript device seems to ignore the par instruction.

I guess one of these is a bug, but I don't know which one!
