No, file_name will typically be a bare name without a directory component. The goal of this code is to produce a path in the current directory if TEST_UNDECLARED_OUTPUTS_DIR is not set. Previously it achieved that by concatenating the empty string with the file_name. Now, it returns file_name directly.
