Nice! Thanks.

Unfortunately this patch does not work with Xapian 0.9.9 or 0.9.10 as
these versions require a non-empty string argument to
Database::postlist_begin. I notice that the patch is in svn so I'm going
to have to go with my nasty patch for now :-(, but hopefully 0.9.11 will
be out soon?

Alternatively, I suppose I could add some term (Xall?) to every document
in the database and use this in the call to postlist_begin(), which
would be safer than my patch, unless there's another non brute force way
of finding the lowest document id in a database?

Cheers
Mark.
