A few of those results are already in CVS, including owl1:268,
auto04:11, and auto_handtalk:7, which all have had their correct
results revised.

This pattern looks slightly bogus. The liberty constraint makes little

doesn't match the referenced position and the reading constraint tries
to play on top of an existing stone.
