How to use:
Install 'git-format-clang' which is part of the clang suite (Fedora:
git-clang-format, openSUSE: clang-tools).
Now do your changes and stage them with `git add`. Once they are staged
format the code using `git clang-format` before you commit.
Now the formatting changed can be viewed with `git diff` against the
staged changes.
