inserted by the user agent for the purposes of line wrapping must be placed
so as to minimise Δ across each run of consecutive lines between preserved
newlines in the source. Δ for a set of lines is defined as the sum over
each line of the absolute of the difference between the line's length and
the mean line length of the set.

This sounds like the "optimal" approach that was--from what I
understand--rejected from CSS because it was O(n^2).  The algorithm I
proposed is is O(n), so it should be possible to change it into a CSS
white-space style later (which is really where it belongs).
