Thanks. I was just thinking that the display engine could somehow do it
noticeably faster, but evaluating that in a large file (xdisp.c) is only
a few milliseconds on my machine, so that's probably fast enough.

Is there going to be a minor mode in the merged version? It would be
nice to have a display-line-numbers-mode-hook to attach the above to.
