(There's a stray closing paren in that output -- fixed.)

I added some more code and managed to auto-convert that monster macro,
arg-ands, from elsewhere in the thread :) The result looks like this:

     (syntax arg-ands
       (quoted-symbol common optional)
       (arg caller optional)
       (sublist
         (arg caller optional)
         (arg variable)
         (arg expr)
         (arg ... rest))
       (arg ... rest))

Still nothing but <code class="syntax def">...</code> added to the HTML.
