note 102527 added to function.header

Doh!  I kept getting the "headers already sent" error message on a header("Location: .....") call.  I checked, re-checked, and re-checked and the scripts nor the files it included had any output - no trailing whitespace, nothing.  I was stumped for quite some time and then realized I had used:

<?php
header("Something Else");
flush(); // !!!!
?>

In one of the includes.  Obviously, when you flush() for the first time it must complete sending the headers, so you can't make any more header() calls!
