Yes, when I did this for my personal projects, I read through the whole
diff and sprinkled /* clang-format off */ everywhere it seemed needed.
It's kind of tedious.  A good thing to do while watching or listening to
something.  :)

If we rename clibrary.h to portable/system.h, it will match the naming
convention in rra-c-util where it largely comes from and will also avoid
this problem.

Yes, agreed.  It looks like that doesn't force any change to existing
formatting either, so I'll adopt that for my own.

Oh, that will be very nice once that's released.  That's one of the
formatting decisions that always bugged me.

I'd be good to go with what's in rra-c-util right now, which is the one I
sent earlier plus the enum change, and I think there was another vote for
whatever as long as it's automated.  Any other thoughts or objections?
