Oh my - I dug through my old branches, and saw that I tried (and failed)
to do this type of cleanup 18 months ago.  Your version is cleaner than
my attempt; I like it.

an error domain we are not familiar with); you should have a catch-all
case that converts NULL to "Unknown".

ACK with that tweak.
