It's tempting, but here's the problem. Let's say someone has a
language list like "en-us, en-gb, en". In this case, the user
preference is for American, then British, and finally generic English.
If our application provides both British and generic English,
following your scheme would result in usage of generic English, even
though the user would prefer British English.
How about a slight modification: first go through the user's list
precisely as specified. If there are no matches, then test the
non-localized version of languages. If there are still no matches,
then use the default language.
