Merge pull request #21 from jenkinsci/pr/20

@ashnazg I amended your commit, but I wasn't able to push another commit to the pull request you started. I didn't find any solution on the web, except to push to the branch you created in your local repository, which I obviously couldn't. If you happen to know how that works, I'd really like to learn that. That said, thanks for the fix - it was only a minor correction I had to make.
