ENH: IOstream::unsetf() now returns old flags (eg, for toggling)

ENH: align MPI_Probe non-blocking handling with header description

- the header states that the commsType is non-blocking or not,
  but the implementation actually checked for 'buffered' or not.

STYLE: fix some spacing and some documentation
