Aargh! I wonder what that would do to DOS paths and stuff like ~username.

I think that's the correct thing to do, but it'll likely break other
stuff. Seems SJIS really isn't suited for Unix command line use. All
the more reason to make EUC-JP the default for "ja_JP" I guess.

I agree. Simply aliasing CP932 to SJIS is wrong, because they are
quite different character sets. Supporting CP932 as a charset in its
own right might be worth considering though, especially as that's the
standard charset on Japanese Cygwin 1.5.
