Partial indentation does not work as described

[chandlerkent]

Describe the bug

Indentation of the partial invocation site is not maintained when the partial is expanded.

From the README:

string source =
@"<h2>Names</h2>
{{#names}}
  {{> user}}
{{/names}}";

string partialSource =
@"<strong>{{name}}</strong>";

Handlebars.RegisterTemplate("user", partialSource);

var template = Handlebars.Compile(source);

var data = new {
  names = new [] {
    new {
        name = "Karen"
    },
    new {
        name = "Jon"
    }
  }
};

var result = template(data);

/* Would render:
<h2>Names</h2>
  <strong>Karen</strong>
  <strong>Jon</strong>
*/

Actual result:

<h2>Names</h2>
<strong>Karen</strong><strong>Jon</strong>

Here is a Fiddle to demonstrate:

Expected behavior:

I expect the indentation of the partial invocation site to be respected when the partial is expanded. This would match other Handlebars implementations I've used, including the "official" npm package handlebars.

You can see the expected output on the Handlebars playground:

I would be happy to work on a Pull Request to resolve this if this would be of interest to the project.

Thanks for taking a look!
