Nested lists are not correctly converted

[oberlies]

There is a newline missing before the indented star (  *) of the first item of the nested list.

Example from samples/Jsonix/Features.xml:

<li>Provides <strong>extensible type system</strong>
	
<ul>
		
<li>Supports most XML Schema simple types</li>
		
<li>Supports enumerations, list and union simple types</li>

This should be converted to

* Provides **extensible type system**
  * Supports most XML Schema simple types
  * Supports enumerations, list and union simple types

However, the current conversion result is

* Provides **extensible type system**  * Supports most XML Schema simple types
  * Supports enumerations, list and union simple types

This should be easy to fix. I'll provide a pull request for this.
