Viewing branch with .json in the name will 404
Created by: jsternberg
This is similar to issue #3132 (closed). If you push a branch that ends with the name ".json", such as "package.json", then viewing the branch will fail.
So if you added a package.json branch to gitlabhq and pushed it, the following URL would fail: http://gitlab.org/gitlabhq/gitlabhq/branches/package.json.
