I put up a patch owl_1_14.1 which addresses comments by Gunnar and
Trevor about patterns to be removed. Since this is a step in the
direction Gunnar and Trevor are advocating I assume it's not
controversial and added it to the CVS.
> A1: Gunnar's defended already - thanks, so perhaps it can be salvaged.
Added as a constraint that the O stone on the 4th line has 3 liberties
or less. If this is true escape is a real possibility and the solid
connection seems probably best.

OK, the patch removes A304.
> A1004: I couldn't see why this made sense.
Sorry, it was A1004 not A1001 that was removed earlier.
> D211: I saw the following match:
I modified the pattern so that match can't occur:
|..O
|..O
|.OX
|.*x
|.x?
The comment (try before hanging connection) and pattern value
suggests why the pattern is there---I believe this came from
a case where the owl code found a non optimal defense, a hanging
connection on the first line where popping out into the open is
obviously bigger.

For the most part I agree. But referring, for example, to A1, there
are probably a few owl patterns for which there apparently isn't a
test case in the db but which are obviously needed.
