Texinfo documentation bug: bad link for GNU GV website

[Christophe Jarry]

Dear developers,

I browsed HTML documentation of Texinfo today and found a bug at section "20.15 
PDF Output" (direct link: 
http://www.gnu.org/software/texinfo/manual/texinfo/html_node/PDF-Output.html#PDF-Output).
 The link for text "GNU GV, a 'Ghostscript-based PDF reader'" links to 
"http://www.foolabs.com/xpdf/";, instead of "http://www.gnu.org/software/gv/";.

Have a nice day,

Christophe
