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.
