If you're currently operating (via Iedit or MC) at positions 10, 42 and
347, then I think it's going to be slightly more efficient if Iedit/MC
runs your command (e.g. self-insert-command, delete-char, you name it)
in the order
run at 347
run at 42
run at 10
then if it does it in the order
run at 10
run at 42
run at 347

Yes, of course, that's what after-change-functions is for.
