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')
