Incorrect documentation about guest permissions
The [public access documentation](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/public_access/public_access.md) says that "Any logged in user will have Guest permissions on the repository."
This is not true because it will have all "guest permissions" plus ["public access"](https://gitlab.com/gitlab-org/gitlab-ce/blob/8581df3bfb9e847d07a585a22cfa21658ae40ea2/app/policies/project_policy.rb#L113-121) permissions
