[docs/pbook.py: correct faulty check for PDF output
Luca Capello <luca@pca.it>**20061002215516
 
 Frank Küster discovered that docs/pbook.py produces buggy LaTeX code,
 a faulty check for PDF output.  It doesn't show up if you only try to
 create PDF.
 
 But if you want to go the traditional route and produce dvi files (and
 from that PostScript and maybe finally again PDF), this will fail and
 still produce PDF.  The script itself doesn't do that (or rather, it
 does that in fact but ignores the output in this first run), but it's
 still an uglyness.  
 
 Moreover, it's completely useless, because the only package that uses
 the information, graphicx, will detect the output format itself (and in
 a proper way).
