title: roxygen2 manually insert line breaks
body: <p>I have a function I am trying to document with roxygen2:</p>
  
  <pre><code>#' Name of function
  #' 
  #' Description
  #' 
  #' @param x The input data
  #' @param method one of:
  #' "method1" - very long text here 
  #' "method2" - very long text here
  #' "method3" - very long text here
  #' "method4" - very long text here 
  #' "method5" - very long text here 
  #' "method6" - very long text here 
  #' "method7" - very long text here 
  #' "method8" - very long text here 
  #' "method9" - very long text here 
  #' "method10" - very long text here 
  myfun &lt;- function (x, method){return(NULL)}
  </code></pre>
  
  <p>This function has about 10 different methods, each of which has a very long description.  I want a newline between each "method," to make it easy to quickly see the different methods available.</p>
  
  <p>As written, when I call <code>roxygenize('mypackage')</code>, the above text get squashed into a single line.</p>
  
  <p>How do I manually insert line breaks into roxygen2 documentation?</p>
