An 'entropy' computation.
However, pure entropy is not a good metric. Entropy for bzr revisions is about
5bits/byte, and entropy for gcc is about 4bits/byte, however
compression for bzr is about 4-5:1, but for gcc it is about 20:1.
This is because the compression is mostly about long substrings that
are the same for gcc.
So instead, we'll just try to tweak the zlib one.
