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).
