Renderd Markdown files had a lot of padding around paragraphs and
headers, which made for an ugly presentation. This change remove that
padding, helping with these common elements.

We likely will have similar issues with other types of content, but this
covers the main cases.

Viewed some Markdown documents. Saw that the text looked a lot nicer.
