An even better alternative has been suggested and implemented, I'm waiting for that version to be tagged in the repository and will then update our base version: The -e and -f option will in general exit after all input has been processed, but an additional "-f -" following those options will allow to supply additional commands via stdin (and thus reproduce the current behavior, if desired).
