Missing hash (#) character in utop example

[kerrickstaley]

In the Variables and Functions chapter there is the following example showing some expressions entered into utop and their output:

# let languages = "OCaml,Perl,C++,C"
val languages : string = "OCaml,Perl,C++,C"
# let dashed_languages =
    let language_list = String.split languages ~on:',' in
    String.concat ~sep:"-" language_list
val dashed_languages : string = "OCaml-Perl-C++-C"

In the PDF version of the book, this gets rendered as:

# let languages = "OCaml,Perl,C++,C" ;;
val languages : string = "OCaml,Perl,C++,C"
let dashed_languages =
  let language_list = String.split languages ~on:',' in
  String.concat ~sep:"-" language_list
;;
val dashed_languages : string = "OCaml-Perl-C++-C"

It seems that whatever processing step that inserts ;; into the rendered output is also eliding the # at the beginning of the third line. I think this symbol should still be there since it represents the utop prompt.

Thanks Kerrick! Assigning to @avsm, who is working on the TeX output.
