Maybe... I need to test globbing files. I was thinking about my use case of single file glob. 
A few lines below is the `Handlebars.SafeString` call. Whether the SafeString needs to be within the `html` block or not I will test now. 

```js
      // promote id into context
      obj.context.id = obj.id;
      var template = Handlebars.compile(options.fn(obj.context));
      return template(obj.context);

    }).join(options.sep);

    return new Handlebars.SafeString(html);
  });
```

So
