I've run into a situation where clang-format does not support the
necessary style rules. It will have to be patched before clang-format is
fully adopted into Sway. Use this file with caution.
CONTRIBUTING.md says use kernel style, "but all braces go on the same line". The
kernel uses a column limit of 80 characters. The de facto syle in Sway is to
allow for wider lines so this format file does not enforce an 80 column limit.
