This is a great idea... Do you know if is this run as part of the build or as a
custom rule they have to remember to run? I guess some additional checking
might be needed to allow bootstrapping this, but I really like this idea of
once a directory is clean keeping it clean because of its part of a normal
build.
Keeping code clang-format clean with all the best will in the world is super
hard, changes drift in very slowly even with asking people to
`git-clang-format` then if one is missing you are asking for what I'm doing
here which is making a clang-format only commit and some don't like that.
