[Exim] headers_add and exim-filters

A forwardfile director is expanding a file to a local user and
adding a header. The header is present after delivery with the
localuser director. However the added header is not available
to the user's exim-filter (~/.forward): it is not enclosed in
$message_headers nor the $header_ variables. The header is
also present if the filter calls the file_transport address_file
with the save command.

Seen on exim-3.14/Solaris7. Is there any way to do local
filtering on headers added by a previous director?
