Indentation bug for sections starting with ^

[nikolas]

mustache-mode correctly indents the closing tag for a section like this:

{{#owners}}
    <li>
        <a class="switcher-choice owner"
            href="{{username}}">{{public_name}}</a>
    </li>
{{/owners}}

However, if the section starts with a caret, this is how mustache-mode indents the region:

{{^owners}}
    <li>
        <a class="switcher-choice owner"
            href="{{username}}">{{public_name}}</a>
    </li>
    {{/owners}}

The closing tag should be on the same column as the opening tag.

I'm using mustache-mode from melpa, v20141024.732, emacs 24.5.50.4.
