Doug,
That was my memory and belief as well. I had already written to KRS pointing out that he/she was ignoring your instructions to check that. It may well be that it is correct most of the time. However, before I said that, I tested in Word 2013. After I checked it in Word 2013, I changed the answer but posted another screen shot of the dialog.
In Word 2013 I accessed the header and created text there. I then returned to the body of the text and made some changes. Then I returned to the header Ctrl+A, Del. When I returned to the body the header was no longer taking up space.
Margins are set to .2 inches. Header and footer distance is set to .5 from edge. You can find this document here.
One thing I did not try was saving with the header before deleting it.
Edit: Same result upon saving with a header, closing, reopening, and deleting the header. No room taken for header.
Just tried with Word 2010 and had same result. document 2010
Also, this was not tried with any alternative headers (first-page/odd-page) in the document.
