    Python 2.7 introduces a backwards incompatible change
    (Python issue1974, r70772) in email.Generator.Generator code:
    pre-2.7 code passed "continuation_ws='	'" to the Header
    constructor, and 2.7 removed this parameter.

    Default argument is continuation_ws=' ', which means that the
    behaviour is different in <2.7 and 2.7

    We consider the 2.7 behaviour to be preferable, but need
    to have an unified behaviour for versions 2.4 to 2.7
