Hi all,

I've discovered an issue with some markdown I'm converting. The unordered lists considers two-spaces an indent, yet the ordered lists need 3-spaces to indent.

I'll pulled the latest and written a test below. Is this the intended behavior? Playing with stackoverflow's stackedit I see two-spaces on a 1. treated as an indent.

Thanks,
Russ

// contains a nested list
var md1 = @"- listitem1
- listitem2
  - two spaces indented
";
// no nested list
var md2 = @"1. listitem1
1. listitem2
  1. two spaces indented
";
// contains a nested list
var md3 = @"1. listitem1
1. listitem2
   1. three spaces indented
";
var pipeline = new MarkdownPipelineBuilder().UseAdvancedExtensions().Build();
Console.WriteLine(Markdown.ToHtml(md1));
Console.WriteLine(Markdown.ToHtml(md2));
Console.WriteLine(Markdown.ToHtml(md3));

The output contains:

<ul>
<li>listitem1</li>
<li>listitem2
<ul>
<li>two spaces indented</li>
</ul>
</li>
</ul>

<ol>
<li>listitem1</li>
<li>listitem2</li>
<li>two spaces indented</li>
</ol>

<ol>
<li>listitem1</li>
<li>listitem2
<ol>
<li>three spaces indented</li>
</ol>
</li>
</ol>

This is a normal behavior of CommonMark list

It depends on the number of characters taken by - or 1. AND the number of spaces after that.

So the following list should be indented like this (note 3 spaces after the first -). Check on babelmark

-   a
    - b

Same for the following list (Check on babelmark3)

10.  a
     1. b
