 		A line starting with ' ', is a continuation line, adding

 		readable context of the message, for reliable processing in
 		userspace.

 		  n8           - netdev ifindex

+		The flags field carries '-' by default. A 'c' indicates a
+		fragment of a line. All following fragments are flagged with
+		'+'. Note, that these hints about continuation lines are not
+		neccessarily correct, and the stream could be interleaved with
+		unrelated messages, but merging the lines in the output
+		usually produces better human readable results. A similar
+		logic is used internally when messages are printed to the
+		console, /proc/kmsg or the syslog() syscall.
