List containing trailing empty list item not followed by a blank line

[neilmayhew]

This test input should be unchanged when rendered back to commonmark:

# abc

  - foo
  - bar
  - 

# def

xyz

Instead, cmark -t commonmark test-case.md produces:

# abc

  - foo
  - bar
  - 
# def

xyz

This happens whether or not the bullet is followed by a space in the empty list item.

The problem is in rendering rather than parsing, because the HTML output is:

<h1>abc</h1>
<ul>
<li>foo</li>
<li>bar</li>
<li></li>
</ul>
<h1>def</h1>
<p>xyz</p>

Also, empty list items are handled correctly when they occur in the middle of a list.

This is a problem for me because I'm trying to round-trip some markdown documents in order to make changes in a different part of the document, and the trip introduces these unrelated and undesirable changes.

Instead, cmark -t commonmark test-case.md produces:

since this isn't a spec issue, shouldn't it be lodged against https://github.com/commonmark/cmark?

I'll transfer the issue.

Thanks for fixing this!
