Subject: Patch #1006219: let inspect.getsource show '@' decorators and add
 tests for this (which are rather ugly, but it'll have to do until
 test_inspect gets a major overhaul and a conversion to unittest). Thanks
 Simon Percivall!

+- Patch #1006219: let inspect.getsource handle '@' decorators. Thanks Simon

 - logging.handlers.SMTPHandler.date_time has been removed;
   the class now uses email.Utils.formatdate to generate the time stamp.
