Please also add tests for common cases

<p>{{#tag}}</p>
<p>Hello world</p>
<p>{{/tag}}</p>

should become {{#tag}}<p>Hello world</p>{{/tag}}

and

<p>{{#tag}}</p>
<p>Hello world</p>
<p>{{/tag}} {{^tag}}</p>
<p>Good night</p>
<p>{{/tag}}</p>

should become {{#tag}}<p>Hello world</p>{{/tag}} {{^tag}}<p>Good night</p>{{/tag}}

Can't you use require('jsdom/lib/jsdom/living/generated/Node.js')?

[Minstel]

<p>{{#tag}}</p>
<p>Hello world</p>
<p>{{/tag}} {{^tag}}</p>
<p>Good night</p>
<p>{{/tag}}</p>

To correctly handle <p>{{/tag}} {{^tag}}</p>, second step (moving tags) is required, when closing tag is first moved out of node. Currently replacing nodes hanles the following cases:

• <p>{{#tag}}</p>
• <p>{{/tag}}</p>
• <p>{{^tag}} {{/tag}}</p>

This is related to current algo - while handling current tags section, it does not look for sibling tags (for better performance), and just consideres them as some data.
I did corresponding change to readme.

@Minstel You should treat {{^tag}} exactly the same as {{#tag}}. A ^ just means 'not'.

If a <p> contains only start and/or end tags, than remove <p>. It doesn't order or number of start tags doesn't matter. Doing step 2 without removing this, means we'll end up with empty paragraphs.
