This can be done with a "column-max-height:100%", assuming we define
percentages to be relative to the height of the multicol element.  (If
you have padding/border/etc, you'll have to use a calc() to get the
value right.)

"width" is the extent in the horizontal direction.  In vertical text,
this is not the same as the inline direction.

We could fix this in the same way we fixed the physical dependency of
top/right/bottom/left, by coming up with a pair of logical-direction
keywords to use in place of width/height.  No one's come up with a
good set yet, though.  (I think last time the discussion came up, we
were happy to use "length" for one of them, probably height, but
couldn't come up with a good one for width.)
