 I haven't checked whether busybox's syslogd does this, but theoretically,
a syslog parser should do this.
 syslog entries are separated by null bytes, so a logging daemon has to
interpret them. But a logging daemon might also want to prepend every
line with its own information (such as a timestamp), so it's also
necessary to understand newlines.
