Differs from os.path.samefile because it does not require paths to exist.
    Purely string based (no comparison between i-nodes).
    >>> same_path("a/b", "./a/b")
    True
    >>> same_path("a/b", "a/./b")
    True
    >>> same_path("a/b", "././a/b")
    True
    >>> same_path("a/b", "./a/b/c/..")
    True
    >>> same_path("a/b", "../a/b/c")
    False
    >>> same_path("a", "a/b")
    False

    Contrary to POSIX 2008, on Cygwin, getcwd (3) contains
    symlink components. Using
    os.path.abspath() works around this limitation. A fix in os.getcwd()
    would probably better, in Cygwin even more so, except
    that this seems to be by design...

    Add the indicated paths to the head of the PYTHONPATH environment
    variable so that subprocesses will also see the packages at
    these paths.

    Do this in a context that restores the value on exit.

    >>> getfixture('monkeypatch').setenv('PYTHONPATH', 'anything')
    >>> with paths_on_pythonpath(['foo', 'bar']):
    ...     assert 'foo' in os.environ['PYTHONPATH']
    ...     assert 'anything' in os.environ['PYTHONPATH']
    >>> os.environ['PYTHONPATH']
    'anything'

    >>> getfixture('monkeypatch').delenv('PYTHONPATH')
    >>> with paths_on_pythonpath(['foo', 'bar']):
    ...     assert 'foo' in os.environ['PYTHONPATH']
    >>> os.environ.get('PYTHONPATH')
