It's unclear what the '!' should negate in case of 'test_path_is_file ! file'. What if 'file' does exists, but it's not a file but a directory, socket, fifo, or symlink? 'test ! -f file' returns success in these cases as well. OTOH, it's quite clear what the negation should mean in case of 'test_i18ngrep'.
