I have some body text including some headers. It would be great to see the CSS3 column property column-break-after support the "avoid" option.

I was able to work around it by surrounding the header and paragraph with a DIV with "page-break-inside: avoid" but that isn't ideal since a very long paragraph won't be able to flow into the next column if needed, but works for my immediate case.

Using avoid on the page-break-after/before properties should also inhibit columns breaks.
