The owl code is not run on all dragons, because when a dragon
has lots of escape room the results are meaningless. The exact
criterion is around line 320 of dragon.c:

 /* Some dragons can be ignored but be extra careful with big dragons. */
 if (crude_dragon_weakness(ALIVE, &no_eyes, 0,
                        DRAGON2(str).moyo_territorial_value,
                        DRAGON2(str).escape_route - 10)
          < 0.00001 + gg_max(0.12, 0.32 - 0.01*dragon[str].effective_size)) {
    DRAGON2(str).owl_status = UNCHECKED;
    DRAGON2(str).owl_attack_point  = NO_MOVE;
    DRAGON2(str).owl_defense_point = NO_MOVE;
  }

If the owl code is not run, then the matcher status is the
crude status and the owl status is ``unchecked''.

The critical status means that GNU Go believes (correctly)
that the dragon can be killed or defended depending on who
moves first. Unfortunately O13 is believed to be a defense
for both O18 and N15 (which are two separate dragons). Of
course O11 is the only move.

Maybe rxvt was compiled without color support. Do you have
any other terminals such as xterm, nxterm, color-xterm etc.?
Any of these terminals can be compiled with color either
enabled or not.
