Adding a nested list element creates extraneous space (markdown_github to html)

[cjerdonek]

It seems like there is a glitch in how nested lists are rendered when converting GitHub Markdown to HTML (checked in Pandoc 1.13.1). For example, this renders fine:

* a
* a
* a

But adding a nested list to the last element:

* a
* a
* a
    * a

causes it to be rendered like this--

* a
* a

* a

    * a

The command I used was--

$ pandoc --from=markdown_github --to=html --output=test.html test.md

It seems to happen because markdown_github enables lists_without_preceding_blankline, which makes the paragraph parser always emit a Para when a paragraph is followed by a list.

Thanks a lot for proposing a patch and test, @neongreen.
