When a buffer has been completely fontified by jit-lock stealth
fontification, that buffer no longer appears in
jit-lock-stealth-buffers.  Is that good enough?

But yes, since stealth fontifications are disabled by default, this
isn't the way to make CC mode fontifications more accurate.

You could still do that, but it could be costly, and slow down
redisplay, no?
