Sorry – I'm confused. You've apparently requested that I review the change again, but it still seems to be in the same state as last time?

There's some code that looks at only the first element of a jump table, and doesn't explain why, and I think it should either check the whole table or have a comment explaining why it doesn't need to. In its current state, it's confusing to readers.
