I've redefined org-babel-ruby-var-to-ruby in my init.el to add a newline 
after each element in an array, which I think will work for anything 
less than a 4k-long string. Ideally, the hard-coded \n would follow the 
EOL convention of the buffer, but I haven't gotten that far yet.


(defun org-babel-ruby-var-to-ruby (var)
   "Convert VAR into a ruby variable.
Convert an elisp value into a string of ruby source code
specifying a variable of the same value."
   (if (listp var)
       (concat "[" (mapconcat #'org-babel-ruby-var-to-ruby var ", \n") "]")
     (if (eq var 'hline)
     org-babel-ruby-hline-to
       (format "%S" var))))
