The end doesn't tell you how long the position list is, it tells you
whether you've got to the end. That's a pretty standard STL-ism.

You can do it another way. Get the Xapian::Document, grab the termlist
begin iterator, skip_to() the term you want, and call
positionlist_count().

If this sort of thing is likely to get used in lots of applications,
with no document context (I can't quickly think of how that might
happen, but I'm probably missing something), it could be added to
Xapian::Database. Possibly not worth the effort, however.
