py3: fix generated non-ascii message in test-notify.t
The resulting "Subject:" header contains an encoded word in Python 3 so
we have to add distinct outputs for Python 3 but underlying values are
the same:
>>> from email.header import decode_header
>>> decode_header('=?utf-8?b?w6AuLi4=?=')
[(b'\xc3\xa0...', 'utf-8')]
{
// Enforcing
"eqeqeq" : true, // true: Require triple equals (===) for comparison
"forin" : true, // true: Require filtering for..in loops with obj.hasOwnProperty()
"freeze" : true, // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
"nonbsp" : true, // true: Prohibit "non-breaking whitespace" characters.
"undef" : true, // true: Require all non-global variables to be declared (prevents global leaks)
// Environments
"browser" : true // Web Browser (window, document, etc)
