The change I proposed (I haven't had time to look at Alan's patch yet,
but IIUC it does what I proposed) does not change the protocol at all.
It just makes jit-lock use the information available in a slightly more
efficient way.

And while the number of packages using jit-lock tends to grow over time,
it's a *very* slow growth, so I think scaling is not
a significant concern.
