    Resolves the given *path* **strictly**, throwing a

    This function exists only because Path.resolve()'s default behaviour
    changed from strict to not strict in 3.5 → 3.6.  In most places we want the
    strict behaviour, but the "strict" keyword argument didn't exist until 3.6
    when the behaviour became optional (and not the default).

    All this function does is call ``path.resolve()`` on 3.5 and
    ``path.resolve(strict = True)`` on 3.6.
