Yes! It uses the old database to speed up reindexing. It checks the dates
in the database so that it can skip as much work as possible. :-) As I
said earlier, it tries not to download documents already in the database.
And if the server sends it and it hasn't changed, it won't bother parsing
But if it HAS changed, it goes about its normal business. It will re-parse
the document, add the URLs to the list to be checked. So new URLs will be
added to the database.

Yup. The point of "update" digs isn't to only ensure the docs in the db
are up to date. The point is to speed up the indexing. If you already have
the information, why bother to collect it again! :-)
