* Fix MPI-2 page number in comments for a specific reference in the spec * Allow getting/setting the errhandler on MPI_FILE_NULL * Allow freeing of intrinsic errhandlers, per MPI-2 errata (if you GET an errhandler on a communicator, you must be able to FREE it, even if it's an intrinsic). Thanks to Lisandro Dalcin for reporting these problems. This commit was SVN r12122.
