[gentoo-dev] [PATCH] glep-0068: Update language identifiers from ISO 639-1 to BCP 47

[Ulrich Müller]

This will allow codes like pt-BR or zh-Hant which is already used
in at least one longdescription in the Gentoo repository.

Note that the L10N USE_EXPAND and GLEP 42 news items also use BCP 47
for language names.
