Yes, that's fine. It should be functionally equivalent to what I posted,
but without having to invoke an extra bash when we are already running
it (and avoiding the giant here-doc, though that is simply ugly and not
a functional problem).

One minor fix. I think it should be:

  exec bash $0 "$@"

to pass arguments (e.g., "-v -i") to the bash sub-process.
