AFAIK, it's the nixos hashed mirror that creates this behaviour. fetchgit itself will re-download if the _basename_ of the URL changes, but when the hashed mirror has a file with the given hash, it is downloaded instead. So it's the hashed mirror that needs to take the basename of URL into account.
