patch for wml::std::toc

["Thomas R. Koll" <nospam@thanx>]

Good afternoon,
Because I need a very special ToC for my geekcode page 
( http://www.tomk32.de/en/geekcode.php ) where the whole ToC is in a single
line. I hope I used diff proper, my version of WML is 2.0.6 (Debian package).
Added is style=nobr
I hope you add it to the official dist
