Attached, rebased over 255f14183ac. This time it's a single .tar.gz.
Let me know if single files are better. Here's the renumbered overview
copied from one of my emails responding to Tom:

-Patches 0001 through 0006 represent a complete one-to-one migration
of data entries. I didn't see much in bki.sgml specific to the current
format, so my documentation changes are confined largely to the
README, in patch 0004.
-Patches 0007 and 0008 implement techniques to make the data lines
shorter. My choices are certainly debatable. There is a brief addition
to the README in patch 0007. The abbreviation technique was only used
in three catalogs to demonstrate.
-Patches 0009 and 0010 implement human-readable OID references.
-Patches 0011 and 0012 are cosmetic, but invasive.
