Hi Martin,
Like Tord mentioned , you can use this info for extensions decisions.
But primary reason why I wanted to rewrite mine was to try out the long check
idea mentioned by Ed.
Preliminary results indicate that it is better than the combination of crazy
bunch of ideas I had earlier , both speed and performance wise :)
So I am moving to Ed's long check version for time being ... (there it helps
immediately - after genEvasion , you know the value to extend the qsearch by).
