I started looking into this. A very minor adjusted patch to filelist.sgml was
required to apply the patch cleanly to current -HEAD (attached).

After reading Joseph's comment upthread, I don't see any consensus wether the
existing pre-9.1 support is required or even desired. Maybe i missed it, but do
we really expect an extension (or contrib module) to be backwards compatible to
earlier major releases, when shipped in contrib/ ?
