This code broke when I upgraded python from 2.2.1 to
2.2.2.  Suddenly, my e-mail is base64 encoded, with no
indication of this in the message header, so the
message body shows up as garbage in my inbox.

I do get a warning:
/home/kevint/bin/e2email:188: DeprecationWarning:
_encoder argument is obsolete.
but it just issues the warning in passing and doesn't
stop it from eating my message.
