Re: [gnugo-devel] Evan's replacement pattern

So I ran the whole regression test, and the delta is as follows:

./regress.sh . nngs2.tst
220 unexpected FAIL: Correct 'S9', got 'T11'
230 unexpected FAIL: Correct 'G17', got 'H18'
240 unexpected FAIL: Correct 'F17', got 'G18'
250 unexpected FAIL: Correct 'T18', got 'N5'
260 unexpected FAIL: Correct 'S18', got 'T12'
270 unexpected FAIL: Correct 'S19', got 'T13'
280 unexpected FAIL: Correct '!A13', got 'A13'
290 unexpected FAIL: Correct 'C17|B16', got 'C18'
300 unexpected FAIL: Correct '!Q13', got 'Q13'
310 unexpected FAIL: Correct 'M11', got 'P8'

However, none of these apply to my patch.  Is this the delta for something
else I missed, or have I managed to screw up something else?

Also, attached is a new version of the pattern.  It should be slightly
more general, and it also passes the test.  I have not run a regression
delta for it yet.

Thanks

Evan Daniel
