Steve, Well, you forced me to download v3.1 (;-). I confirmed your results in the SQLite shell; I think it's a bug. Also, there are some typos in the docs: the section on short_column-names is labeled full_column_names, and there are words missing from both sections. I think probably someone should write a bug ticket.
