No, that's not what the man page says the option does. That option
keeps anything but errors being sent to standard error; it has no
relationship to the system log.

Pick the dhclient messages up in a different log file.
Something like (untested):
!dhclient
*.* /var/log/dhcpd

Yep, your lease time is 10 minutes long.

Try setting your dhclient.conf to ask for a longer lease. If that
fails, pull the dhclient messages into another file...
