Cannot seem to use to_formatter within custom

[smondet]

I think it could be because of the call to flush https://github.com/mjambon/easy-format/blob/master/src/easy_format.ml#L620

What I'm trying to do looks like:

custom (fun ppf ->
   (* .. bunch of pp_stuff ... *)
   List.iter a_few_easy_format_dot_ts ~f:(fun ef ->
      (* ... *)
     Easy_format.Pretty.to_formatter ppf ef
      (* ... *)
   ) ;
  (* ... more pp_stuff ... *)
)

What are you expectations and what error are you getting?

In the example above, I am expecting ef to be properly indented and formatted, but after the first one, they seem to show up non-indented and breaking "boxes" (that's why I think it is because of the call to Format.pp_print_flush).

If I replace Easy_format.Pretty.to_formatter ppf ef with fprintf ppf "random stuff" the same code seems to be correctly formatting the output.
