Upstream 6564b87c2f6dac2482e530bc43b038a3e93a0e07
resolves #6, include last record in language-subtag-registry.xml

The '%%' in language-subtag-registry is a record delimiter, not record
end marker, it is not present on the last record at file end.

(cherry picked from commit 4fff73a834f94a7ca256c086d99ea0a654a6c287)
