Good point. I'd like to have the code look a little clearer
though. Lengthy "... && ... && ..." chains are fine as one shot command
lines, but are not useful in real code. Thus:

sudo-command-line() {
    [[ -z $BUFFER ]] && zle up-history
    if [[ $BUFFER != sudo\ * ]]; then
        BUFFER="sudo $BUFFER"
        CURSOR=$(( CURSOR+5 ))
    fi
}

Objections?
