Subexpressions does not work with composed properties

[beradrian]

HTML:

<script id="template" type="text/x-handlebars-template">
<ol>
    <li>{{dash 'abc' (concat a b)}}</li>
    <li>{{dash d (concat a b)}}</li>
    <li>{{dash c.c (concat a b)}}</li>
    <li>{{dash (concat a b) c.c}}</li>
    <li>{{dash (concat a e.e) c.c}}</li>
</ol>
</script>
<div id="rendered"></div>

JavaScript:

Handlebars.registerHelper('dash', function(a, b) {
    return a + "-" + b;
});

Handlebars.registerHelper('concat', function(a, b) {
    return a + b;
});

var template = Handlebars.compile($("#template").html());
$("#rendered").html(template({a: 'a', b:'b', c:{c:'c'}, d:'d', e: {e: 'e'}}));

jsfiddle: http://jsfiddle.net/beradrian/6T8ah/

The actual result is

1. abc-ab
2. d-ab
3. c-[object Object]
4. ab-c
5. ae-[object Object]

and it should be

1. abc-ab
2. d-ab
3. c-ab
4. ab-c
5. ae-c

This is not failing under master. I don't know exactly what resolved this, but it may be related to #749.
