Surround a heredoc with quotes and you can continue the code on the same line:

    render :status => 404, :text => <<-'EOH' and return unless setup
        article not found<br/>
        I, as a server, have failed<br/>
        https?
        EOH

Quotes also give you more freedom/creativity with the terminal ID:
