Description of problem:
If you log a syslog message that contains embedded newline characters, journald truncates it at the first newline character.  This became clear because the default snmptrapd logging formats include embedded newline characters.  Most of the message is discarded as a result.

Version-Release number of selected component (if applicable):
systemd-204-17.fc19.x86_64


How reproducible:
Try running this:

bash-4.2$ logger 'this is
> a test message with some
> embedded newlines'

Then observe that only "this is" appears in the journalctl output, and in
/var/log/messages.

In Fedora 14 with rsyslogd, one sees the full message in /var/log/messages:

Nov 12 14:17:14 ti119 schorr: [ID user.notice] this is#012a test message with some#012embedded newlines


Steps to Reproduce:
1. logger 'this is
> a test message with some
> embedded newlines'
2. journalctl -n
3.

Actual results:
[root@ti124 test]# journalctl -n 100 | grep this
Nov 12 14:16:41 ti124 schorr[23125]: this is


Expected results:
The full message with escape sequences for the newline characters.
