Trivial change (formatting).
Temporary fix for change in PETSc interface.

Branch knepley/fix-faults-parallel will provide complete update/fix.
Merge branch 'knepley/fix-faults-parallel'

* knepley/fix-faults-parallel: (51 commits)
  Turn off more debugging output (PETSc).
  Turn off journal output in full-scale test.
  Update mesh info for 3d/tet4 embedded fault full-scale tests.
  Faults: Fixed checking for cross edge - I needed to throw out non-fault edges when checking the support size
  Update test data for 3d/tet4/TestShearDispNoSlipRefine (may need another update).
  Faults: Added missing destroy
  Faults: Fix completion of fault boundary label
  Updated tests_auto/3d/hex8 embedded fault settings (fault edge).
  Remove binary Exodus file (keep ASCII mesh file).
  Updated tet4k mesh file.
  Updated test data for adjusting topology for tet4k (embedded fault).
  Fault Test: Fixed data for Hex8j - Fault cells have 5 vertices since 3 are clamped per cell - Fault label includes split points
  Fix fault edge group.
  Use nonzero tolerance for detecting inability to determine face orientation with respect to up direction.
  Added unit test for adjusting topology of tet4 cells w/embedded fault.
  Created unit test for adjusting topology for hex8 cells w/embedded fault.
  Faults: Removed the creation of the fault boundary mesh - Also removed non-interpolated code for fault creation
  Enable fault edge in 3d/tet4 embedded fault test.
  Updated 2-D tri3 refinement w/embedded fault case.
  Updated data for tri3 full-scale test with embedded fault w/edge.
