gcc-12 detects redundant check against array of arrays as:

    src/plugins/python_api.c: In function ‘python_api_register_command’:
    src/plugins/python_api.c:199:31: error: the comparison will always evaluate as ‘true’ for the address of ‘c_arguments’ will never be NULL [-Werror=address]
      199 |         while (c_arguments[i] != NULL && c_arguments[i][0] != NULL) {
          |                               ^~
