[ragel-users] wide finder in ragel

[Adrian Thurston]

There is an error in this which affects correctness seriously and
performance slightly. The :> operator should really be :>>. Meaning that
we stop the [^\n]* machine when the search pattern finishes, not when it
starts. In the previous version any "G" ahead of the "GET ..." will fail
the pattern.
