Hi, I'm trying to revive and improve Gerbil integration with Geiser. Gerbil's interpreter is run with `gxi -` with `-` being simultaneously "run in interactive mode" and "do not load init file". So I load file manually here: https://gitlab.com/greenfork/geiser-gerbil/-/blob/master/elisp/geiser-gerbil.el#L314
But init file also shows a greeting message with `(displayln gerbil-greeting)` which is not displayed in Geiser. Could I get any suggestions on how to show this greeting message in REPL before prompt `>`?
