[chef] Re: torrent hash is same for every torrent after the first

[Chris McClimans < >]

http://tickets.opscode.com/browse/COOK-729

https://github.com/opscode/cookbooks/blob/master/transmission/providers/torrent_file.rb#L117

Thanks to fujin for the help on #chef. Nice to know there are other
New Zealanders doing great things with chef.

Cheers,
