> For giving more weight to short words, my gut feeling is this is too steep. A simple and less steep function would be "1 / (1 << length)":

Just for completeness, using that last function instead:

20046g, 66877p/g 0:00:01:00 0.00% 328.9g/s 21999Kp/s 21999Kc/s 1295GC/s

Not better in this test. Maybe I should do this after each test:

$ cut -d: -f2 ../run/john.pot | perl -e 'foreach (<>) { chomp; $l{length()}++ } foreach (sort keys %l) { printf("%d%10d\n", $_, $l{$_}) } '
0         1
1         7
2         7
3       275
4       653
5      1411
6     11667
7      5174
8       851

...and maybe I should do all tests with --max-len=10 as well. So many alternatives.
