    Warning rather than attempting to correct TERM
    
    Lunar^ points out that setting the user's TERM could cause issues. Replacing it
    with a warning...
    
    atagar@morrigan:~/Desktop/arm$ TERM=rxvt-unicode-256color arm
    Unknown $TERM: (rxvt-unicode-256color)
    Either update your terminfo database or run arm using "TERM=xterm arm".
