Hello Alik,
Patch applies, compiles, works (I checked the distribution). Doc gen ok. make check ok.
I have reduced range to [1, 10] and updated the test.
I would suggest to use [1, 9] and the simpler regex [1-9] instead of the full list.
Also, there should be an empty line between functions. I just noticed that one is missing after zipfFindOrCreateCacheCell().
