You don't need to "cobble together complicated variables" here. Just
printf straight away to stdout.

On the occasion when you do need to justify/pad a parameter without
printing, you can use `printf -v` or this:

    % n=10
    % y=${(r:n:: :)}  # n spaces
    % x='hello'
    % z=${(r:n:: :)x}  # right-justified x

There is also l (lower-case L) for left-justification.
