Clearly not ... case-only rename on a case-inseneitive file-system
assumes that the file-system is case-insensitive. :)

That's a no-op. You've not renamed Zig.

That's a case-only rename of Foo/Zig to Foo/zig.

You're really piling it on here, starting from wrong premises. :)
A rename affects the last component of a path, nothing more. I've never
heard of a system when you can case-only rename a directory in the
middle of a path.

In short, things aren't /that/ tricky as far as renames go. They're a
lot trickier during update and commit, if the editor hits a local file
that has the wrong case on-disk, but is otherwise versioned (I've known
brain-dead tools to case-only rename the files they'd worked on).
