How would I use PetscObjectReference((PetscObject)section) in Fortran?

call PetscObjectReference(section,ierr)

Its not wrong. This is the way I wanted it. You set the PetscSection and give up control. If you do not want to give up control, then call PetscObjectReference() before passing it in.

Since this is (a) different from everything else in PETSc and (b) not explicitly documented, it is doubly wrong.
