-----------------------------
Versions information

root at arachide:~# lsb_release -rd
Description:	Ubuntu 14.04.1 LTS
Release:	14.04

root at arachide:~# apt-cache policy lxc
lxc:
  Installed: 1.0.6-0ubuntu0.1
  Candidate: 1.0.6-0ubuntu0.1
  Version table:
 *** 1.0.6-0ubuntu0.1 0
        500 http://fr.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     1.0.3-0ubuntu3 0
        500 http://fr.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

-----------------------------------

lxc-info output is different when displayed directly in the terminal or
redirected to a file


Expected: same content when displayed in term or redirected to a file
Actual result: contents different


This behavior broke a custom script which was working like a charm on Ubuntu 13.10 with lxc version 1.0.0~alpha1 amd64. This is working correctly as well on Ubuntu 14.10 with the stock trusty version of lxc in the main repo (1.0.3)

How to reproduce:

root at arachide:~# lxc-info -n my_lxc
Name:           my_lxc
State:          STOPPED
root at arachide:~# lxc-info -n vfc-sla > test.txt
root at arachide:~# cat test.txt
Name:           my_lxc
Name:           my_lxc
State:          STOPPED
Name:           my_lxc
State:          STOPPED
Name:           my_lxc
State:          STOPPED
Name:           my_lxc
State:          STOPPED
Name:           my_lxc
State:          STOPPED
Name:           my_lxc
State:          STOPPED
