3 changes to poudriere

These three commits are tested extensively on 3.0.3 and briefly on 3.0.13. One of them is a solution to ticket "864f8d25712d8d9f96443acfe9b1de9948e58976" on your site. All three should be fairly independent of each other (there might be some issues with the man page changes).

Enjoy and let me know about any issues. :)
