util.human.io: Support for dynamic "proportional" columns Instead of a percentage, this allows you to specify e.g. `width="[N]p"`, where a width="2p" will be twice the width of a width="1p" column. Compatibility with the old %-based widths is preserved, and percentages adding up to more than 100 are handled more gracefully.
