I was already anticipating that possiblitiy and my inital patch description
is along these lines.

However, liblzf is BSD licensed so on the license side we should be fine.
Regarding patents, your last comment was that you'd like to see if it's
really worth it and so I have included support for lzf for anybody to go
ahead and find that out.

Will send an updated split up patch this weekend (which would actually be
four patches already...).
