Fixed test case for mediawiki (tilt)

Actually I don't know if this is useful, but I just wanted to check out how the new tilt feature works.

Actually I have 
- Added `title="Edit section: Section"` to the `<a>` tag
- Fixed a few new lines and `<p>` tags
- Changed `<dl><dd>Each colon at the start of a line` to `<dl><dd>Each colon at the start of a line</dd></dl>`

I hope this one will pass Travis.
