[Suppress-Script] Initial list of 300 languages

[Caoimhin O Donnaile]

John,

(Copying this to a few people who'll hopefully put me right if
I say anything which is wrong)

Regarding the question of which languages should be given a
"Suppress-Script" tag (on the grounds that the "overwhelming majority") 
of documents in the language are written in that script and therefore
script specification is unnecessary), I can answer for the Celtic
languages and Scots.

   cy  Welsh
   gv  Manx
   br  Breton
   gd  Gaelic, Scottish Gaelic
   kw  Cornish
   sco Scots

These should all have a Supress-Script of Latn.
(I see that Welsh and Manx already have Supress-Script:Latn
in the Language Subtag Registry at:

   http://www.iana.org/assignments/language-subtag-registry

and that the other four have Latn in your initial set of "70 answers".

However, it seems to me that Latn is wrong in your "70 answers" for:

   sga Irish, Old (to 900)
   mga Irish, Middle (900-1200)

and also wrong for:

   ga  Irish

which is already in the Language Subtag Registry, and therefore
may need correcting.  All of sga, mga, and gv were customarily written 
in the Latg script (i.e. with dotted-consonants rather than 'h' 
following the consonant), but could also be written in Latn, too,
at least in modern transcriptions.

It is certainly true that the "overwhelming majority" of documents
now being written in Modern Irish (ga) are in Latn, but up til the
1950s the majority were in Latg, and many books were published in
Latg for a decade or two after that.  There are pages in the Internet
written in Latg, and with the coming of Unicode their number is
likely to increase.

Admittedly, the difference between Latg and Latn is not very great,
especially compared to the likes of Cyrl and Hant, and Latg is
only a "variant" script, but if it counts as a separate script, then
it seems to me to be wrong to give any of sga, mga or ga a
Supress-Script of Latn.
