[Mpi3-hybridpm] slightly improved document is posted

[William Gropp]

Though it is syntax (so don't worry too much about it yet), it is  
error prone to have different terms/objects differ in a single  
character.  It is faster to type, but the lost time from typos  
(inserting/forgetting the "E" in "EWORLD") more than equals any  
savings.  So once the semantics gets nailed down, and *no earlier*, it  
would be good t think carefully about the name.
