====== Comment Empty Lines ======

By default commenting of the code skip empty lines and do not place comment mark on them. 

This code: 
<code javascript>
var a = 1;

a = a + 10;
</code>

To enable commenting of **empty** lines too, and getting something like this:
<code javascript>
//var a = 1;
//
//a = a + 10;
</code>

add into <Formatting> section **settings.xml** following key:
<code xml>
<Formatting>
        <CommentEmptyLines>true</CommentEmptyLines>
</Formatting>
</code>
