read-tree: add tests for confusing paths like ".." and ".git" We should prevent nonsense paths from entering the index in the first place, as they can cause confusing results if they are ever checked out into the working tree. We already do so, but we never tested it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

read-cache: optionally disallow HFS+ .git variants The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for HFS+; let's use it in verify_path. We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on HFS+. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectHFS config option. Though this is expected to be most useful on OS X, we allow it to be set everywhere, as HFS+ may be mounted on other platforms. The variable does default to on for OS X, though.

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.
