ENH: allow disabling of initial MPI_Comm_dup(MPI_COMM_WORLD,...) 

- can use -mpi-no-comm-dup to suppress the initial communicator
  duplication (to avoid potential deadlock with coupled processes).
  This is partly related to comments in merge-request !735

ENH: simplify parsing/removal of local -world option

- can extract the world name in a single pass and also makes the
  parsing robuster.
