I understand that, but what would be broken (that was not broken already
in libgcrypt-1.4.x) if the GCRY_MPI_FMT_USG was declared as default for
gcry_sexp_nth_mpi() ? Is there currently any known use in existing
software that expects the GCRY_MPI_FMT_STD if 0 is specified as format
in gcry_sexp_nth_mpi()?
