In looking at multiple occurrences and values for issues like #2692, I noticed that `...` can mean both multiple values and multiple occurrences, like before we split them. Pros - No syntax change with clap3 Cons - All the reasons we split `multiple` into two Uncertain - I originally started this as part of another branch but I lost track if something depended on this. I'll have to do more digging BREAKING CHANGE: If `--opt [val]...` was meant for - only multiple occurrences, see `[opt]... --opt [val]` - both multiple occurrences and values, see `[opt]... --opt [val]...`
