Here is an edited version of the documentation note. Please review to
see if you like my version.
Also, I fixed a compiler warning.
My tests showed a significant reduction in the size of a gist index with
many of the same penalty values. The run times showed mixed results,
however, and I didn't dig in much further because you've already done
significant testing.
Marking this one ready again.
