testing vger handling of charsets (part 2)

This is a test message to check how vger reacts to seeing 8bit
characters (like Hasselström) in a message _with_ the right mime
header.

If your mail server doesn't advertise the 8BITMIME extensions, I expect
this message to come through OK, since vger will (hopefully) respect the
existing content-type header. Karl and Bruce, can you please report?
