• With glob expansion, search_paths can become empty when the user explicitly provides only glob patterns that match nothing (or invalid patterns). In that case this code will now fall back to adding cwd, which changes the prior semantics where explicit search_paths disabled the default cwd behavior. Consider only defaulting to cwd when options.search_paths is None (not provided), not when it was provided but expanded to zero matches.

    if search_paths.is_empty() {
        if let Ok(cwd) = env::current_dir() {
            search_paths.push(cwd);
        }
    }
