commit 7f676fb7cf34dd2982d0cf79aeea7e5b06ad91eb

    vt: fix background color on line feed, DEC invert
    
    Original report: """I used to force my console to black-on-white by
    the command `setterm -inversescreen on`. In 2.6.26-rc4, I get lots of
    black background characters."""
    
    Another addendum to commit c9e587ab.
    This was previously missed out since I was not aware of what
    vc_decscnm was for.
