Markdown markup question

[Jan Erik Moström]

If I have the following text
---------------------------------------------------
Just a small test

     This is some code

         and some indented code

and this is the end

1.  Just a small test

         This is some code

             and some indented code

     and this is the end
---------------------------------------------------
This results in
---------------------------------------------------
<p>Just a small test</p>

<pre><code>This is some code

     and some indented code
</code></pre>

<p>and this is the end</p>

<ol>
<li><p>Just a small test</p>

<pre><code>This is some code


<pre><code>and some indented code
</code></pre>

</code></pre>

<p>and this is the end </p></li>
</ol>
---------------------------------------------------

Note that there are two code tags for the list, is this to be 
expected? have I missed something? is it a bug? or should I just 
learn to live with it?
