[css3-multicol] pseudo-algorithm

The pseudo-algorithm [1] to detemine the number width of columns
currently prescribes:

  width: 100px; column-gap: 49px; column-count: 3 /* results in 3 columns of 0.66px each */
  width: 100px; column-gap: 50px; column-count: 3 /* results in 2 columns of 0px each   */
  width: 100px; column-gap: 51px; column-count: 3 /* results in 1 column  of 100px */

The very narrow columns are problematic. Implementors may impose
minimium column widths. Unless the specification gives guidance on
what the minimum width should be, we are likely to see different
solutions.
