Currently (trunk, just svn update'd), the following call fails
(because of the ranks=NULL pointer)
MPI_Group_{incl|excl}(group, 0, NULL, &newgroup)
BTW, MPI_Group_translate_ranks() has similar issues...
Provided that Open MPI accept the combination (int_array_size=0,
int_array_ptr=NULL) in other calls, I think it should also accept the
NULL's in the calls above... What do you think?
