+Original commit URL, which also shifted directory structure:

++** dropped as appropriate.
++**
++** SQLite core adds the custom function fts2_tokenizer() to be used
++** for defining new tokenizers.  The second parameter is a vtable
++** pointer encoded as a blob.  Obviously this cannot be exposed to
++** Gears callers for security reasons.  It could be suppressed in the
++** authorizer, but for now I have simply commented the definition out.
