[RFC][BZ#13985] missing language in iso-639.def

[Chris Leonard]

Resolution of the issue in [BZ#13985]
"cgg Chiga (Rukiga, Ruchiga, or Kiga maybe) missing"

https://sourceware.org/bugzilla/show_bug.cgi?id=13985

would seem to require addition of a single line to locale/iso-639.def

Given that Chiga only has an ISO-639-3 code (and not an ISO-639-2 code)


Which of the following lines is the correct addition to make?


DEFINE_LANGUAGE_CODE2 ("Chiga", cgg)    /* ISO 639-3 */


or is it


DEFINE_LANGUAGE_CODE3 ("Chiga", cgg, cgg)


The first construction is only used once in iso-639.def, whereas the
second construction seems more common in that file in similar cases.
