How does this cope with the case insensitive case preserving file systems on Mac and Windows, esp when core.ignorecase is true. If it's a bigger problem that the series already covers, would the likely changes be reasonably localised?

This came up recently on GfW for `git checkout` of a branch where the case changed ("Test" <-> "test"), but git didn't notice that it needed to rename the directories on such an file system. https://github.com/git-for-windows/git/issues/1333
