Option to keep empty lines

[shawnsz]

It would be great if we can have an option to keep the empty lines.

Example input:

<var config=data.config/>
<var pageQuery=data.pageQuery/>

<div class="reset-link" if(filterGroup.resetLink)>
          <shui-textual-display model=filterGroup.resetLink/>
</div>

Current output:

<var config=data.config/>
<var pageQuery=data.pageQuery/>
<div class="reset-link" if(filterGroup.resetLink)>
  <shui-textual-display model=filterGroup.resetLink/>
</div>

Output (Keep the empty lines):

<var config=data.config/>
<var pageQuery=data.pageQuery/>

<div class="reset-link" if(filterGroup.resetLink)>
  <shui-textual-display model=filterGroup.resetLink/>
</div>
