Angular recursive ng-include when tracking recursion depth

Question

I have a situation that is pretty similar to this answer to the question here:

AngularJS ng-include with nested hierarchy

I have some data in the format

 $scope.data = {
text: "blah",
comments: 
[
  {
    text: ["blahL11", "blahL12", "blahL13"],
    comments: [
      { 
        text: ["blahL111", "blahL112", "blahL113"] 
      },
      { 
        text: ["blahR111", "blahR112", "blahR113"] 
      }
    ]
  },
  {
    text: ["blahR11", "blahR12", "blahR13"] 
  }
]

};

And I show it with recursive ng-include as follows:

  <ul>
   <li>{{data.text}}</li>
   <li ng-repeat="item in data.comments" ng-include="'tree'"></li>
 </ul>

 <script type="text/ng-template" id="tree">
  <ul>
    <li ng-repeat="text in item.text">{{text}}</li>
    <li ng-repeat="item in item.comments" ng-include="'tree'"></li>
  </ul>
</script>

However, I would like to somehow track the depth of the recursion. To instead of a simple display:

-blah
    -blahL11
    -blahL12
    -blahL13
            -blahL111

It can display

-1. blah    
    -2. blahL11
    -2. blahL12
    -2. blahL13
        -3. blahL111

Without me, changing the data structure (since depth is only for display?). Can I insert a variable into ng-include, is there some kind of recursive index $ that I can use?

, ng-init. , , .

plnkr

<li ng-repeat="item in item.comments" ng-include="'tree'" ng-init="depth = depth + 1"></li>
