document formatter inserts unnecessary whitespaces

[SchabaJo]

Hello!

Formatting an XSLT document (others not tested) results in otherwise empty lines filled with spaces to reach target indentation level.
Here is an example, select text to view differences:

Before:

<book>
    <author>
        <firstname>John</firstname>

        <lastname>Doe</lastname>
    </author>
</book>

After:

<book>
    <author>
        <firstname>John</firstname>
        
        <lastname>Doe</lastname>
    </author>
</book>

It can help to have the indentation when editing the XML, I propose adding a "Keep indents on empty lines" setting that defaults to true (as this is the current behaviour). Other editors provide this option too.
