As a (probably much higher rated than e000) pillar humping paladin on retail in WotLK, I can say without a doubt that this commit is wrong. The cast should fail at the end. If someone is casting a spell on you and you run out of LoS and then back into LoS before the cast ends, it will finish and hit you. You have to be out of LoS at the time the cast ends for it to fail.
