Function ilc::seen

pub fn seen(
    nick: &str, 
    ctx: &Context, 
    input: &mut BufRead, 
    decoder: &mut Decode, 
    output: &mut Write, 
    encoder: &Encode
) -> Result<(), Error>

Return the last message of a given nickname, searching from the beginning of the logs. Will return Err if the decoder yields Err. This relies on absolute timestamps, and behaviour without full dates is undefined.
