If I have a markdown file

```ocaml
# let f = function
   | "" -> false
   | _ -> true
val f : string -> bool = <fun>
```

it gets accepted by ocaml-mdx test.

However, for the same file in .mli:

(** {[
# let f = function
   | "" -> false
   | _ -> true
val f : string -> bool = <fun>
]} *)

then ocaml-mdx test will complain that the first line is not ending with a ;; and report a syntax error, as the first line is considered as a complete block.

$ cat blibli.mli.corrected 
(** {[
      # let f = function;;
      Line 1, characters 17-19:
      Error: Syntax error
    ]} *)
