There is ‘cursor-sensor-functions’, but it requires
‘cursor-sensor-functions’ to be on. IIUC you want the squiggly lines
remain invisible until point leaves the overlay, right? You probably
have thought of this, but what about simply checking whether there is
any whitespace character between point and the word being checked,
before creating the overlay? Would that work?
