[R] eps Portrait to pdf now rotated since gs6.5 --- why?

[Prof Brian D Ripley]

I have now managed to trigger this.  The solution is to remove the
%%Orientation comment in the .eps.  *However*, according to the
PostScript Language Reference Manual this is to be used by viewers to set
the window orientation, so gs is not following the DSC guidelines.  It
seems only to use it for pdf and not say png conversion.

I'll remove that comment when producing eps from postscript(), as it also
affects bitmap().
