Add a space before code block info strings

This is for consistency with the `cmark` style. Now the blocks we still
pretty-print ourselves will match the bulk of them that `cmark`
produces.

Ensure that Records keep their syntax after being added to the codebase

Record with 1 field

unique type Record1 = { a : Text }

scratch/main> view Record1

  type Record1 = { a : Text }

Record with 2 fields

unique type Record2 = { a : Text, b : Int }

scratch/main> view Record2

  type Record2 = { a : Text, b : Int }

Record with 3 fields

unique type Record3 = { a : Text, b : Int, c : Nat }

scratch/main> view Record3

  type Record3 = { a : Text, b : Int, c : Nat }

Record with many fields

unique type Record4 =
  { a : Text
  , b : Int
  , c : Nat
  , d : Bytes
  , e : Text
  , f : Nat
  , g : [Nat]
  }

scratch/main> view Record4

  type Record4
    = { a : Text,
        b : Int,

        d : Bytes,
        e : Text,
        f : Nat,

Record with user-defined type fields

This record type has two fields whose types are user-defined (Record4 and UserType).

unique type UserType = UserType Nat

unique type RecordWithUserType = { a : Text, b : Record4, c : UserType }

If you view or edit it, it should be treated as a record type, but it does not (which is a bug)

scratch/main> view RecordWithUserType

  type RecordWithUserType
    = { a : Text, b : Record4, c : UserType }

Syntax

Trailing commas are allowed.

unique type Record5 =
  { a : Text,
    b : Int,
  }


  Loading changes detected in scratch.u.

  I found and typechecked these definitions in scratch.u. If you
  do an `add` or `update`, here's how your codebase would
  change:
  
    ⍟ These new definitions are ok to `add`:
    
      Record5.a        : Record5 -> Text
      Record5.a.modify : (Text ->{g} Text)
                         -> Record5
                         ->{g} Record5
      Record5.a.set    : Text -> Record5 -> Record5
      Record5.b        : Record5 -> Int
      Record5.b.modify : (Int ->{g} Int)
                         -> Record5
                         ->{g} Record5
      Record5.b.set    : Int -> Record5 -> Record5
    
    ⍟ These names already exist. You can `update` them to your
      new definition:
    
      type Record5
