Describe the bug
Below, the %expect has no newline before {|, but %%expect does put a newline before {|. The newline is unnecessary.

;;
[%expect {|
___________________________________________________________
|}]

[%%expect
  {|
___________________________________________________________
|}]

How to Reproduce
I get the above formatting using ocamlformat built from b28bb02 using --profile=janestreet.
