I use Emacs sh-script mode and I end up with things looking like this

case foo in
  (bar)
  do_foo_bar
  ;;

  (rod)
  do_foo_rod
  ;;
esac

which is pretty much your second option, except there's no additional
indentation after the test and the separate ;; serves
as a visual end marker (like a "break" in C).  The zsh code seems to be
full of things like:

case foo in
  (bar)
    do_foo_bar
    ;;
  (rod)
    do_foo_rod
    ;;
esac

sometimes with a space between the ;; and the next test, sometimes without,
sometimes with the ;; level with the test, sometimes indented as shown.
However, there are other variations, too, including having the ";:" on the
same line as the last chunk of code, which seems to be more common when
there's only one line of executable code (which then sometimes appears on
the line with the test).

The only consensus seems to be the "(bar)" test is indented from the
"case".
