* Fixes trac:338: Only look at root-significant values at the root (e.g.,

recvbuf in MPI_GATHER).
 * Minor style updates (constants on the left of == and !=)
 * Fix a minor buglet that crept in r11904: had a recvbuf where it
   should have been recvcount.  Thankfully, this would have only
   affected erroneous programs.  ;-)
