[Suppress-Script] Initial list of 300 languages

In that case, that code did not comply with RFC 1766, which provides
a specific set of syntax rules for language tags.  The types "xx" and
"xx-yy" are only a small subset of the full syntax.  (RFC 3066 extended
this syntax, and RFC 3066bis *restricts* it.)

Specifically, the language tags "i-ami", "i-bnn", "i-default",
"i-klingon", "i-lux", "i-mingo", "i-navajo", "i-pwn", "i-tao", "i-tay",
"i-tsu", "no-bok", "no-nyn", "zh-gan", "zh-guoyu", "zh-hakka", "zh-min",
"zh-min-nan", "zh-wuu", and "zh-yue" were all valid RFC 1766 tags as of
the publication of IPP/1.1, and a system claiming conformance to that
protocol cannot validly reject them.

(Some of these tags are or will be deprecated, but none were deprecated
at the time.)
