The reword looks better, but it's actually not just a correctly-indented GROUP, it's:
+<li>adding a correctly-indented GROUP (<code>\\</code>) or "special comment"
(such as #|...|#)  on each blank line</li>

If you're going to list *all* the possible ways, special comments will do the same thing:
aa bb
! cc dd
! #| more stuff |#
! ee ff
; => (aa bb (cc dd) (ee ff))

Of course, changing a blank line to a ;-only line is usually the better approach!!

Yes, a non-empty comment works too.
I think he meant a ;-comment-only line, optionally preceded by indent characters.
