The spec says "In continuous media, this property will only be consulted if
the length of columns has been constrained. Otherwise, columns will
automatically be balanced." Unfortunately "constrained" is completely
undefined :-(. (Your use of the word "unbounded" is undefined too :-).) The
phrase "continuous media" is also obsolete now that we can have columns
flowing into arbitrary regions. It also seems odd to have the fact that a
page-break might exist far away from an element with columns affect the
layout of those columns.

I think it would be simpler to remove that paragraph and just make the
property always apply. This means when the element's height is auto and
max-height is none, and there's no pagination or region stuff happening,
column-fill:auto will put all the content in the first column, but that's
OK IMHO; 'auto' is not the default value, and authors should only use it
where it makes sense.
