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.
