I'd like to try this one, and request for another RFC.

Now, because the old tools still do the parsing of this format, we can
add a new field called prev_state_char that will give you this. Now to
save space, we should change prev_state to int (can't make it short as
there's that test for "+" which does sometimes happen). I believe we
can make prev_prio and next prio into shorts (and possibly chars!).

Or just leave the thing alone?

Sure, but I would like to change the fields to smaller ones just so
that the event wastes less space on the buffer.
