Markdown bug GitLab 6.1

Created by: samrocketman

When you create a link in markdown to nested markdown in a README.md for a project then links are not properly referenced in the main Files page for the project.

e.g. [docs](docs/doc.md) will link to /<namespace>/<project>/tree/docs/doc.md when viewed in the Files tab but when viewing the README.md file directly it will correctly reference /<namespace>/<project>/blob/<branch>/docs/doc.md.
