[Mpi-22] Empty members and MPI_TYPE_GET_CONTENTS

[Jeff Squyres]

FWIW, I don't particularly care whether we return the 0's or not -- I  
just want the ambiguity resolved so that all MPI implementations do  
the same thing.

That being said:

a) Dick makes some pretty good arguments.  I can see the value of not  
returning the 0's.  If we voted again, I'd probably vote to not return  
the 0's.

b) I *think* the predominant attitude in the forum for the straw votes  
was "what the heck; might as well return the 0's since that's what was  
originally passed."  I don't recall there being any other strong  
technical reason.

Specifically: if we take a new straw vote and go the other way  
(*don't* return the 0's), I'll happily change the proposal to reflect  
that and we can start it over again (ie., have first reading, etc.).
