Notes from in-office discussion:

* 'git clang-format --style file -f --extensions c,h'
   to apply suggested changes. (Useful for contributors,
   maybe even as a precommit hook)
* you can also give a range of commits to git clang-format, as
   git clang-format --diff origin/master..HEAD to see if other
   local commits need tweaking.
