Thanks for all the help and testing! Pushed. If we don't come up
with something better I'll need to figure out how to explain this in
the manual. (Will no one rid us of these meddlesome old format locale
names? It seems like pg_locale.c could drop a lot of rather
unpleasant code if initdb, CREATE COLLATION, and CREATE DATABASE
didn't allow them into the catalogue in the first place...)
