When using a non-ASCII, 7bit "sending charset" (such as ISO-2022-JP) the
message headers are not being properly encoded, per RFC2047.  The
MIME::encode() function appears to be using only the "is8bit" check in
deciding to encode the text, regardless of whether or not it's ASCII.

The result of this is that the resulting mail headers end up being displayed
as "raw" ISO-2022-JP text, which is "gibberish" to the user.
