clang-format (since 10) can output diagnostics which indicate
lines needing formatting with --dry-run and -Werror: the exit
code indicates if a file is correctly formatted or not.

We used to copy each .cpp file, run clang_format on the duplicate
and then `cmp` to see if there were changes made, before just
printing a line with the filename and moving the new ontop of
the original.

Now we show clang-format diagnostics which indicate which
lines will be changed, prompt for confirmation and then let
clang-format modify the files in-place without the juggling.

Looks like this: https://user-images.githubusercontent.com/291142/184561633-c16754c8-179e-426b-ba15-345ba65b9cf9.png
