Is it possible to preserve extra line breaks when using [input-xml: yes] [indent: yes]

Say xml input is:

<root>
<a><b>c</b></a>

<a><b>c</b></a>
</root>

When I run with:
input-xml: yes
indent:yes
indent-spaces:2

It strips the newlines:
<root>
  <a>
    <b>c</b>
  </a>
  <a>
    <b>c</b>
  </a>
</root>

I would rather have the output to be:

<root>
  <a>
    <b>c</b>
  </a>

  <a>
    <b>c</b>
  </a>
</root>

Is there an parameter I can set so it preserves extra newlines? I am
trying to copy the behavior of MS Visual Studio 2008.

Thanks!
