-- To reply to myself: Having looked at the "file" db pattern source 
[1], I see that the "file" maintainer introduced a typo into the 
matching pattern for correctly identifying Classification records. 
That's way it's failing for Class records.

Don't know if you consider these "bulk," but there is more than 1 record in each file (caveat: "file" stops after evaluating the first line, so of the 2,574 Auth records, the last 2,573 could be invalid).  It failed on a file containing all of LC Classification.  I need to figure out why.
