Line removed between list and preceeding text

[cconover]

Originally opened as an issue for Atom Beautify

When creating a list in a markdown file, the beautifier removes the blank line between the end of the preceeding text and the beginning of the list. So what starts out like this:

Here is some sample text.

- List item
- List item

Here is some more text.

Ends up like this:

Here is some sample text.
- List item
- List item

Here is some more text.

While GitHub's markdown parser seems to be able to handle this, many others cannot and so lists end up being broken.

Whoops, I opened an issue without reading to see if it was already reported. My mistake!
