There's an unfortunate formatting wart with VTK_OVERRIDE in headers and empty default implementation bodies, but it's split out into a separate commit for easier handling.
The checks now hit .txx files which were not handled in the previous formatter which adds these files to the set for formatting: Examples/Catalyst/CxxMappedDataArrayExample/vtkCPMappedVectorArrayTemplate.txx, ParaViewCore/ServerImplementation/Core/vtkSIVectorPropertyTemplate.txx, ParaViewCore/ServerManager/Core/vtkSMRangeDomainTemplate.txx.
