Status of BSD Diff replacement?

[Matthew Story]

Just wondering what the current status is on a BSD diff replacement.  The
IdeasPage suggests that a goodly amount of work was done on this for GSoC
2010 (http://wiki.freebsd.org/IdeasPage#BSD-licensed_Text-Processing_Tools),
but the GPLinBase page says it's unowned and suggests replacement with
OpenBSD diff (http://wiki.freebsd.org/GPLinBase).

Wondering how much is outstanding on this, and where to start reading to
catch up on what's been done?
