[issue1690608] email.utils.formataddr() should be rfc2047 aware

[Torsten Becker]

Torsten Becker <torsten.becker at gmail.com> added the comment:

I implemented a basic test for the issue and an attempt for a fix.

I am not entirely sure with my implementation, specifically I would like to get comments concerning the following points:

  - Is is OK that formataddr() will now check if address is ascii safe and if not it will raise a UnicodeEncodeError?
  
  - I was not sure on the style how to append new tests to test_email.py, I just put it into the same spot where all the other formataddr() tests where, shall I put it to the end instead?


I am submitting this patch as part of my preparation for the Google Summer of Code to familiarize myself with the contribution process, any feedback on what I should do different is very welcome.
