Relative links in base README.md incorrect

Given I've created a repo guides.git that contains e.g.

-
 |- CONTRIBUTING.md
 |- GETTING_STARTED.md
 |- README.md

When my README.md contains.

# Index of guides

* [Getting Started](GETTING_STARTED.md)
* [Contribution Process](CONTRIBUTING.md)

Then if I view the repository /guides/browse (i.e. do not view the README.md file directly, but get the implicit rendering when viewing a repository's page) then the links do not resolve correctly, they resolve to /guides/GETTING_STARTED.md.

If I view the README.md file directly /guides/browse/README.md, then I correctly get them resolved /guides/browse/GETTING_STARTED.md
