While I think I can see why you'd do it that way in earlier Emacsen,
I think the better way to do it nowadays is to simply arrange for the
region highlighting to extend to to whole lines.

You can do that with redisplay-(un)highlight-region-function, which was
introduced to allow rectangular-region-highlighting.
