It's more than just that. There are a number of additional checks that are performed for the benefit of various insane filesystems like HFS and NTFS. For example: HFS has several codepoints that are ignored for the purposes of name comparison; for example, U+200C. We need to protect against those, too, or else you could have ".git<U+200C>/config" in your repository that maps to ".git/config".
