contains a table that is likely a source for Nicolas' commit:

Contemporary babel.pdf contains another table (1.13 ini files)

de-1901    German
de-1996    German
de-AT-1901 Austrian German
de-AT-1996 Austrian German
de-AT      Austrian German
de-CH-1901 Swiss High German
de-CH-1996 Swiss High German
de-CH      Swiss High German

I am still unsure that de and de-de should be mapped to different babel 
language configurations.
