Yeah the result doesn't look too good and I'm not sure which option to
tweak for that. I'm sure that the problem would fix itself if all the
bit fields where defined on their own lines:
unsigned force : 1;
unsigned not_new : 1;
... etc ...
I'm sure there are a bunch of other things that we'd need to tweak
before this is ready to be used by all contributors. Specifically the
penalties to help determine when to break a line.
