In the end, I coded up a direct use of jit-lock-force-redisplay in a
one-time timer. The reason I preferred this over font-lock-flush is that
j-l-f-r says in its doc string that it forces a redisplay, whereas f-l-f
merely says it declares (BEG END) as being out of date.
I hope to post my proposed new code on emacs-devel soon.
