++Valid values are yes,true,no and false. This option enables new syslog format
++which is suitable for logging. Every change is logged as one simple line. This option
++changes verbose level to 0 and prints everything that was changed. It is suggested
++to use this option with "report_url=syslog:...". Default value is "false/no".
++Maximum size of message is 1KB which is limitation of syslog call. If message is
++greater than limit, message will be truncated.
