* Update comments in some MPI_FILE_* functions to reflect that the MPI specs have different page numbers in the ps and pdf (woof!). * Update comments to say "Retain" where we meant retain (not "return) * Add a check in MPI_ERRHANDLER_FREE to raise an MPI exception if the user attempts to free an intrinsic errhandler *and* the refcount is 1 (meaning that it would actually free the intrinsic). This protects erroneous programs from segv'ing. * Remove lengthy comment from comm_get_errhandler.c which is no longer valid (because of the MPI-2 errata that says that users *do* have to call MPI_ERRHANDLER_FREE).
