Sofor crossplatform behavior on Windows, it should escape symbols on commandpassed to cmd.exe that are special to this shell to avoid breaking Pythonscripts. What you propose is a bad workaround, because it assumes that allPython users who use subprocess to execute hg or git should possess aprioriknowledge about default subprocess behaviour with default shell on Windowsand implement workaround for that.-- anatoly t.-------------- next part --------------An HTML attachment was scrubbed...URL: <http://mail.python.org/pipermail/python-dev/attachments/20140614/9f23e89d/attachment.html>
