Filesystems and case-insensitivity

File and directory names are a problem too, of course. If a directory you're storing in git includes both foo and FOO, then you'll have a problem when you try to check it out on a case-insensitive filesystem.

I don't think that's really fixable; some people actually do have such content which they need to track in git, others can't deal with it, it's up to the user to decide what they care about.

But git works on case-insensitive filesystems if the stuff you put into it does.
