Lout and Ensure section headers are not cut off from their bodies

[Jeff Kingston]

I did some quick tests and things seemed to be working well.  I
observed that section headers appeared near the bottom of the page
only when at least the first two lines of the section also appeared;
when there was room for less than two lines, the section title
moved to the second page.

If you have an example with a problem, send it along.
