win32: assign winstdout to sys.__stdout__ as well (
issue2888)
On Windows sys.stdout was being replaced with winstdout, which caused
util.system() to redirect its output (due to
406b6d7bdcb9). That causes
interactive tools (such as vim) to stop working.
To run the tests, do:
cd tests/
python run-tests.py
