[Paraview-developers] [vtk-developers] New git commit hooks

[Berk Geveci]

I was just describing the conversation I had with Brad. The idea was
to have checks only for things that screwed up the history (like
merging from next to master) or possibly things that could corrupt
people's repositories (I believe an example for that was screwed up
line feed). We were not supposed to have commit checks for anything
you listed. I somehow don't believe that we are enforcing 79 character
or less. If we are, we should stop. Same with trailing white spaces.

Brad, can you chime in here please.
