Jyrki Alakuijala 90fcfcd905 Insert less hash chain entries from the beginnings of long copies.
This makes the chains more efficient and a larger variety of data is tested.

0.02 % compression gain at q 100, 0.05 % at default quality. 0.8 % speedup by
callgrind.

0.16 % compression gain for lossy alpha ?!
