verify_dotfile(): reject .git case-insensitively
We do not allow ".git" to enter into the index as a path component, because checking out the result to the working tree may causes confusion for subsequent git commands. However, on case-insensitive file systems, ".Git" or ".GIT" is the same. We should catch and prevent those, too. Note that technically we could allow this for repos on case-sensitive filesystems. But there's not much point. It's unlikely that anybody cares, and it creates a repository that is unexpectedly non-portable to other systems.
