note 69056 rejected from function.flush by didou

Note Submitter: kamermans at teratechnologies dot net ---- If you use the flush() command, even if you haven't sent anything to the browser, the headers_sent() command will return true. If you are trying to flush an empty buffer before checking if the headers are sent, they will always appear sent. This is contradictary to the documentation since the output buffer doesn't store headers.
