i would have written ${1-} so -u can be used.

also: i really think that using terminators as "continuation"
ease the code reading because

* it makes code more aligned
* it's easier to spot a different terminator than ;;

case "${1-}"
    in ('')     do_nothing
    ;; (hello*) greetings
    ;| (*world) greetings # twice
    ;; (long)
        multiple commands
        comes in indented lines
    ;;
esac

regards
marc
