Indeed, I was only counting the number of records, not the number of 
subtags, so that a record like this:

Type: language
Subtag: qaa..qtz
Description: PRIVATE USE
Added: 2005-10-16

counted as only 1 instead of 260.  My bad.

I'm always curious about the math in posts like this, or like Ken's 
occasional "How many Unicode characters?" posts, so I'll want to go back 
and do it myself anyway.  One thing I would note is that the number of 
redundant tags makes no difference in the final count.
