E.g. the following snippet produces multiple lines of output, due to
pretty-printing

  #+BEGIN_SRC ocaml :exports code :eval no-export :results verbatim
(* Note, no need to have parentheses around sqrt, as
application binds the tightest *)
let rec gamma n = if n = 0
                   then (1.0 +. sqrt 5.0) /. 2.0
                   else 1.0 /. (gamma (n-1) -. 1.0)

let nums = List.map gamma (List.init 5 (fun x -> x))
  #+END_SRC

  #+NAME: gamma-tbl
  #+RESULTS[1fd6a3e846afdef51350eb6d7ba15c6844ccc14e]:
: val gamma : int -> float = <fun>
: val nums : float list =
:   [1.6180339887498949; 1.61803398874989468; 1.61803398874989535;
:    1.61803398874989357; 1.61803398874989823]

(In reality this would have 50 or so outputs, point being mathematically
it shouldn't change, but due to floating point errors it does.)

The regexp has the following problems:

- The "." in group 5 (as-was) doesn't match new-lines, so it only
   matches the first line, e.g. as a list
   : - [1.6180339887498949, 1.61803398874989468, 1.61803398874989535,

- When using "\\(.\\|\n\\)", it includes the starting indentation of the
   list, which makes org-babel-script-escape choke (called from
   org-babel-ocaml-read-list, from org-babel-ocaml-parse-output, from
   org-babel-execute:ocaml, the code being modified.
