    w: don't truncate if we're writing libxo json/xml
    
    If we're writing structured output (i.e. json or xml) we shouldn't worry
    about terminal width, and instead always output full width information.
    
    This means that, for example, if we're called from crontab with 'w
    --libxo json' we'll provide full the command field rather than
    pointlessly truncating it.
