Having reviewed the mailing list discussion around tzdb.tar.lz, I now
understand that the era of desynchronised tzcode and tzdata releases is
over, so this wrinkle doesn't apply to downloading current versions.
For historical versions, I'm managing the split versioning by baking
into my downloading code a table of all the historical releases since
1993 (including a couple that weren't announced on the mailing list;
I think I got them all).

So of the issues I discussed, the only one getting in the way of me
using HTTP(S) is the lack of a machine-friendly way to determine the
version number of the latest release.  To reiterate:
