Indents for list items not rendering from .md input file

[citkane]

Docco 0.8.0

Given a .md input file with:

-.List
....-.item1
....-.item2

docco renders

<ul>
    <li>List</li>
    <li>item1</li>
    <li>item2</li>
</ul>

The indents are not rendering (tried with ..- and ....-).

However, given a .js input file with:

//-.List
//....-.item1
//....-.item2

docco renders:

<ul>
    <li>List
        <ul>
            <li>item1</li>
            <li>item2</li>
        </ul>
    </li>
</ul>

indents render just fine.
