I see nothing wrong using continue before `do`.   I've used it a lot
of times and I never had issues with it.  It is useful when trying to
imitate `do {} until ...`, or `do {} while ...`.

However, I won't mind if it just skips checking `$?` when an explicit
control command like `continue` is used since it's more sensible that
way.  Currently, `continue` is just synonymous to `break` when used in
an `until` loop, and I find that counter-intuitive.  Four others
shells don't behave that way.
