[AUCTeX] pstricks and TeX-PDF-mode

[Mandar Mitra]

Hello,

I use xetex as my default TeX-engine, and it seems to handle pstricks without 
any problems, but style/pstricks.el contains the following:

    780    (unless (member "pst-pdf" TeX-active-styles)
    781      (TeX-PDF-mode-off))

So whenever I use the pstricks package, I have to turn TeX-PDF-mode on by hand. 
Would it be ok to change the above to:

(unless (or (member "pst-pdf" TeX-active-styles)
            (eq TeX-engine 'xetex))
   ...

Irrelevant aside: xelatex handles included eps, pdf and jpg images, UTF-8 text, 
and as far as I can tell pstricks so much more easily than pdflatex. Are there 
some downsides to it as well? I.e., is pdflatex better than xelatex at doing 
anything?
