After a quick look at the code, I don't think there is anything
problematic about the data representation or the decompression
algorithm. The compression algorithm is another story, and it's
not real well commented :-(. The important issues are how you
search for matches in the past text and how you decide which match
is the best one to use. Please update the code comments to describe
that, and I'll take another look.
