You don't need to delete the overlay and make it again each time, just
use `move-overlay'. You can also move an overlay that's been deleted,
essentially recreating it, so long as you still have a reference to it.

translation environment package I've been thinking of for a while, and I
just wrote pretty much the same code a couple of days ago :)
