[gnugo-devel] another regression patch

[Gunnar Farneback]

This patch adds 14 new regression tests.

atari_atari:16
Finds a bogus combination attack due to intricacies with how the
atari_atari code handles its goal array.

blunder:22
Filllib makes a backfilling move which happens to reduce a small
eyespace, making the group owl attackable.

blunder:23-27
Playing an outer liberty causes the outcome of a semeai to become
worse.

reading:172
Simple reading mistake. I already have a fix for this.

score2: 60
Scoring mistake, revealing an incorrect assumption in the aftermath
code.

strategy5: 273, 274
The atari_atari code comes up with bogus defense moves.

strategy5: 275, 276
Basic semeai problem. White can make a corner seki (275) and black can
live with territory (276). The latter test case passes.

strategy5: 277
The correct move is undervalued compared to some other moves which the
atari_atari code has identified as defenses.


The function blunder_size() in utils.c has this notice (which I added
in my last revision):

  /* FIXME: We would also need a detect_semeai_blunder() to check
   * against moves which make the outcome of a semeai worse, e.g. by
   * letting the opponent live in seki.
   */

The five test cases blunder:23-27 all are examples where this is
needed.
