Feature request: break -S (syslog) out from -f (don't detach)

[somercet]

Hi! I switched from Arch to Void, and am now on musl, runit, dcron and rsyslog (hugs rsyslog, I missed you sooo much).

Like systemd, runit does not detach jobs. Currently, Void runs dcrond alongside 'logger -p cron.notice' because '-f' not only stops detaching, it also turns off syslog.

Would you accept a patch for '-S' to keep syslog on, to allow it to override the no-syslog part of '-f'?

Thanks for reading!
