Issue

Trailing white space is removed in /var/log/messages.

Steps to Reproduce:
1. Use the logger command with a trailing white space:

[root@localhost ~]# logger "TEST "

Actual results:

[root@localhost ~]# cat /var/log/debug.log 
Debug line with all properties:
FROMHOST: 'localhost', fromhost-ip: '127.0.0.1', HOSTNAME: 'localhost', PRI: 13,
syslogtag 'root:', programname: 'root', APP-NAME: 'root', PROCID: '-', MSGID: '-',
TIMESTAMP: 'Jan  2 11:30:18', STRUCTURED-DATA: '-',
msg: 'TEST'
escaped msg: 'TEST'
inputname: imjournal rawmsg: 'TEST'

The trailing white space is removed as above.
