Having lc_collate return a value which is silently being ignored seems
to me rather hugely confusing.

Also, somewhere along the line someone broke initdb --no-locale, which
should result in C locale being the default everywhere, but when I just
tested it it picked 'en' for an ICU locale, which is not the right
thing.
