avoid markdown which the repl's :doc cannot handle

Browse source 
code blocks, if not surrounded by empty lines, have the language
tags (in these cases, always `nix`) show up in the output of :doc.

for example:

  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example: nix builtins.parseFlakeRef
    "github:NixOS/nixpkgs/23.05?dir=lib"  evaluates to: nix { dir =
    "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type =
    "github"; }

is now instead:
  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example:

      | builtins.parseFlakeRef "github:NixOS/nixpkgs/23.05?dir=lib"

    evaluates to:

      | { dir = "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type = "github"; }

(closes #225)

*`derivation reference`* must be a string that may contain a regular store path to a derivation, or may be a placeholder reference. If the derivation is produced by a derivation, you must explicitly select `drv.outPath`.
This primop can be chained arbitrarily deeply.
For instance,
```nix
builtins.outputOf
(builtins.outputOf myDrv "out)
"out"
```
will return a placeholder for the output of the output of `myDrv`.
This primop corresponds to the `^` sigil for derivable paths, e.g. as part of installable syntax on the command line.
