Commit f64903fd81764f1fde7aeb00eea5e1d488458f63 by joachim
Add -Wno-error=unknown flag to clang-format.

Currently newer clang-format options cannot be included in .clang-format files, if not all users can be forced to use an updated version.
This patch tries to solve this by adding an option to clang-format, enabling to ignore unknown (newer) options.
