-international: trailer

[Rainer Gerhards <rgerhards@hq.adiscon.com>]

Hi WG,

as I am editing -international, I noticed that the TRAILER specified may
be worth looking at. Now that we do not need to remain
backward-compatible, I would opt to have a simple tailer in the message.
It was defined as:

 SYSLOG-MSG      = PRI HEADER MSG [TRAILER]
 TRAILER         = [CR] LF

While the trailer is not strictly necessary to form the message, I think
it is quite a good sanity check if the message looks OK.

Of course, I will continue to edit the draft as this is a minor issue.

Any comments?
Rainer
