Multiline help text with indentation

Sample

I altered the test.fsx file to try this out.

let fileOption =
  commandOption {
    names ["f"; "file"]
    description "Name of a file to use\n\
                 Default index: 0\n\
                 Look multiple lines!\n\
                 Neat!"
    takes (format("%s:%i").withNames ["filename"; "index"])
    takes (format("%s").map (fun filename -> (filename, 0)))
    suggests (fun _ -> [CommandSuggestion.Files None])
  }

I did not push those changes ^ they were just for manual testing. Would you prefer some code added for that?

Thank you very much for your contribution! Looks good to me in general. I will be doing the versioning and creating a release myself, so can you revert the last commit bumping the version?

Alright! Sure enough :)
