I would nevertheless be glad if you would write something up about them,
so we have it in the records should we ever re-examine this issue.

No, no.  I implemented the full three-byte variation as it is, for
instance, implemented in glibc as well.  Cygwin converts the CP 20932
doublebyte sequences for JIS X 0212 into Unix compatible triplebyte
sequences and vice versa.  So Cygwin applications see a Unix-like
eucJP implementation, not a CP 20932 implementation.
