There is only one reason I can think of and that's so it is shown in
the title bar of ghostview.  That's a pretty good one.  I never use
default filenames, so the name in the title bar is always informative
if it's the filename.  All my postscript files created by R are in
places where it's obvious they're R Graphics Output.  That might not
be the case for other people.

I looked at it, and noticed I'd have to do things with the .Internal
PS function (and I'd been warned off going there).  I asked the R-help
list how complicated it would be and was promptly notified that it had
been changed in the R-devel.  That's one of the neat things about R:
things happen quickly.

I'm not complaining.  It's simple enough for me to work with how it
is.  There was a possibility that other people might think my way of
working wasn't so wierd so that a change to the default might be
desirable.  I never use onefile = FALSE so there could be issues that
complicate matters in a way I'm unaware of.
