Blank lines inside code blocks are not preserved in HTML output

[xenomachina]

If I have the following KDoc:

 * ```
 * This is a test
 *     of Dokka's code blocks.
 * Here is a blank line.
 *
 * The previous line was blank.
 * ```

the resulting (non-Javadoc) HTML looks like this:

<pre><code>This is a test
    of Dokka's code blocks.
Here is a blank line.
The previous line was blank.</code></pre>

The blank line below "Here is a blank line." is missing.
