title: Disable auto fill mode in noweb-mode
body: <p>Please for the love of god how can I make Emacs stop auto-filling? I use <code>visual-line-mode</code>, I do not want auto fill. I can turn it off with <code>M-x auto-fill-mode RET</code> but in Noweb mode it gets turned back on when I move into a code chunk and back out again. Please, I just want to globally turn of auto fill mode, it's driving me crazy.</p>
  
  <p>I've tried</p>
  
  <pre><code>(auto-fill-mode 0)
  </code></pre>
  
  <p>and a bunch of crazy things like </p>
  
  <pre><code>(add-hook 'Rnw-mode-hook '(lambda () (auto-fill-mode 0)))
  (add-hook 'latex-mode-hook '(lambda () (auto-fill-mode 0)))
  </code></pre>
  
  <p>But nothing seems to work. Please help me.</p>
