I recommend running this in the libMesh dir:
find . -name '*.[Chi]' -or -name '*.py' | xargs perl -pli -e 's/\s+$//'
Then adding a commit hook to the repository that never again allows
trailing whitespace to enter.
Then it doesn't matter if people keep it out using Emacs or a Git
pre-commit hook... but you won't ever get spurious diffs again.
Like Cody says, we implemented this policy over 2 years ago... and it has
been working like a champ.
