Those are new tests, with no relation to your patch.

Don't bother with the regressions. It's clearly way too general.

Consider e.g.

|....
|X.X.
|OX..
|.OXX
|.OOO

or

|...X
|..X.
|X..X
|OXXO
|.OOO
|....

or

|XXX.
|...X
|X..X
|OXXO
|.OOO
|....

You really can't do without a reading constraint for this pattern,
unless you make it extremely specific.
