interleaving fences and inline code

Code
  cat(out1$get_value("details"))
Output
  Details 10

  \if{html}{\out{<div class="sourceCode r">}}\preformatted{y <- x + 10
  y
  #> [1] 20
  }\if{html}{\out{</div>}}

preserves white space

Code
  cat(out1$get_value("details"))
Output
  \if{html}{\out{<div class="sourceCode r">}}\preformatted{a <- 1

  b <- 2
  }\if{html}{\out{</div>}}

  \if{html}{\out{<div class="sourceCode r">}}\preformatted{c <- 3
  }\if{html}{\out{</div>}}
