Wouldn't 0% *also* resolve to "auto" for cases where things *were*
"able to flex", but the flexbox didn't have a definite width/height?
Though I suppose this would happen in the layout algorithm, and we
could just *specify* what happens.

If this does end up working, I like using it over a new keyword, not
least because I still can't think of a good name for it.
