The test coverage we get with "make run_examples" is abysmal, but
it would have caught any obvious errors with those PETSc versions,
and I haven't noticed any subtle errors with petsc-2.3.1.  I'll commit
your patch (with a slight assert() reordering John suggested) to CVS
tonight; I don't think it'll break anyone else's code either.

For those who want to experiment with algebraic multigrid, try the
latest CVS.  The options "-pc_type hypre -pc_hypre_type boomeramg"
seem to be a good start.
