Issue Summary

When using a Markdown list without a preceding blank line will render the items on a single line. Note that this is acceptable in traditional Markdown (as per Markdown.pl), however in the CommonMark spec, it is noted that lists do not need a preceding blank line.

Steps to Reproduce

1. Suppose the following code is part of a Markdown formatted file:

       I need to buy
       - new shoes
       - a coat
       - a plane ticket
       

Expected Results

The code is rendered as follows:

I need to buy

• new shoes
• a coat
• a plane ticket

Actual Results

The code is rendered as follows:

I need to buy - new shoes - a coat - a plane ticket

Workaround

Use the Markdown.pl style lists which require a blank line before the list.
