From: Tao Klerks <tao@xxxxxxxxxx> On case-insensitive filesystems, where core.ignorecase is normally set, the index is still case-sensitive, and surprising outcomes are possible when the index contains states that cannot be represented on the file system. Add an "expect_failure" test to illustrate one such situation, where two files differing only in case are in the index, and a "reset --hard" ends up creating an unexpected worktree change.
