gitlab.rb extra_sign_in_text does nothing
(Gitlab 8.0.4) As documented here: http://doc.gitlab.com/ce/customization/welcome_message.html, the gitlab.rb extra_sign_in_text setting should add/change the Gitlab CE login page. It does not, no change is visible on the login page or in the login page code.
Using the "Sign in text" text-box under admin > settings, does add the text so I'm guessing the documentation needs updating?
If someone could confirm this I could update the documentation if you'd like.
