[Mpi-comments] MPI_Get_count_x

Hi, I think, that function MPI_Get_count_x (const MPI_Status *status, MPI_Datatype datatype, MPI_Count *count) is missing. After use of function MPI_Status_set_elements_x, MPI_Get_count is possibly not able to return a compatible value. This is contradictory to Page 483, Lines 22-33. Hubert
