Excuse me, I am using `email.message_from_string` which is documented
to convert a unicode string to an email object. If you are serious
`message_from_string` should not even exist! As long as it is there
and documented as::

  email.message_from_string(s, _class=email.message.Message, *, policy=policy.compat32)

    Return a message object structure from a string. This is exactly
    equivalent to Parser().parsestr(s). _class and policy are
    interpreted as with the Parser class constructor.

    Changed in version 3.3: Removed the strict argument. Added the
    policy keyword.

your argument is unfounded and this is definitely a serious bug!

I'm using Python 2.7 and only just exploring 3.5.

Unfortunately, there are many bugs and your response is a typical
example why moving from 2.7 to 3.x is hard.

There is gratuitous breakage but the reaction is::

    resolution:  -> not a bug

I would ask you to reconsider that stance.

As long as my code needs to support 2.7, use of any new API doesn't
fly. After an eventual switch to 3.5 (probably years in the future), I
might use new APIs for new code but changing existing code that used
to work won't be in the cards

Thanks for the hint. BTW, removing the leading newline doesn't change
the buggy behavior of `message_from_string`!
