The referenced commit added a fiche_options because fiche_args would get
eaten by daemon(8). Adjust the pkg-message to reflect reality that the
mentioned "-S" needs to go to fiche itself.
PORTREVISION bumped so that consumers actually get the fixed message,
though nobody's complained about it until today it seems.
Fixes: 6b13f9598ed5 ("net/fiche: enable passing options such [...]")
