Update all cc code using .clang-format; please do so as well for future PRs etc.; emacs has a handy 'clang-format' mode to make this automatic. For comparing old changes with git blame, we can disregard this one using --ignore-rev (see https://www.moxio.com/blog/43/ignoring-bulk-change-commits-with-git-blame )
