Although intentional, this is not quite correct if we follow the
Unicode CLDR, which considers the ‘default’ Norwegian is ‘no’
(technically it’s a macrolanguage, and ‘nb’=“Norwegian Bokmål” is
empty and just inherits from it). This is the correspondence made
by babel, which follows Unicode. However, internally, hyphenation
rules are set to the name ‘norwegian’ as set in language.dat,
which loads ‘nb’, which, in turn, loads ‘no’, so in the end it
works as it should 🙂.
