Amazingly enough it doesn't seem to. Regression results are

endgame:931     PASS R16 [R16]
endgame:960     PASS J10 [J10]
semeai:48       PASS 1 0 D8 [1 0 (D8|F8|G12|G10)]
semeai:147      PASS 1 1 B15 [1 1 (B15|C15|D15|E15)]
gifu05:1110     PASS L5 [L5]
5 PASS
Total nodes: 1703011843 3335518 12414098 (+0.022% +0.051% +0.027%)

Of these semeai:48 and semeai:147 are properly solved, endgame:931 is
random, and endgame:960 and gifu05:1110 are both a bit lucky but good.

Additionally it properly solves testcase 16 of STS-RV_0 and testcases
32 and 49 of STS-RV_1.

This patch has by far the best impact to size ratio I've seen in a
long time. :-)
