in version 6.7.1 and older, the option format generates new lines, so the following xml text

<?xml version="1.0" encoding="UTF-8"?>
<root><a><b><c value="1"/><d value="2"/></b></a></root>

becomes this one

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <a>
        <b>
            <c value="1"/>
            <d value="2"/>
        </b>
    </a>
</root>

but int 6.8 this option does format but without generaing new lines, so the text becomes this other

<?xml version="1.0" encoding="UTF-8"?>
<root><a><b><c value="1"/><d value="2"/></b></a></root>

so it can't be used as xml indentation tool as I used to.

I don't know if this is a bug or a feature, but at least there should be an option to decide if new lines should be added or not.
