After such a change there is the following breakage:

./regress.sh . trevora.tst 
370 unexpected PASS!
./regress.sh . nngs.tst 
820 unexpected FAIL: Correct 'J13|L9', got 'D14'
./regress.sh . semeai.tst 
59 unexpected PASS!
60 unexpected FAIL: Correct '0 0 PASS', got '1 1 H5'
./regress.sh . strategy4.tst 
155 unexpected FAIL: Correct 'D18', got 'E16'
./regress.sh . ninestones.tst 
560 unexpected PASS!
./regress.sh . 9x9.tst 
30 unexpected PASS!
120 unexpected FAIL: Correct 'F1', got 'B1'

[There will be one more unexpected pass from the beedee game
at move 280. I added tests from this game as semeai:99 and 100.]

The tests trevora:370 and 9x9:30 already passed in the CVS.
Some of the others you already discussed in your e-mail
http://mail.gnu.org/archive/html/gnugo-devel/2004-01/msg00065.html.

What we get is two new unexpected fails at nngs:820 and
strategy4:155.

For nngs:820, W's now likes D14 and you have to admit there
is something to be said for fighting the semeai. It is not
clear to me that D14 is not the right move.

For strategy4:155, however, it is clear that D18 is a better
move than E16.

It seems to me that this breakage is acceptable, but we
might want to take a look at whether something can be
done about strategy4.
