Looks good. Feel free to add it as a ticket at http://trac.gnugo.org
as well.

While we're talking about semeai, I've realized that I have forgot to
mention a fairly comprehensive semeai test suite with no less than 722
tests! It has been compiled by Ricard Vilà and can be found at
http://gobase.org/reading/preview/Semeai/#STS. Although it's in GTP
format it uses a custom command solve_semeaiS so it would be good to
adapt it to the normal GNU Go commands. For more information and a
solve_semeaiS implementation, see
http://trac.gnugo.org/gnugo/ticket/41.
