This fix is to support win32 files in fotmat: \\?\drive:\dir\name.ext It's valid file format in win32. I've got that kind of file name trying to use __file__ when script is used as isapi extension.
It's not clear to me what the intention of this patch is: it is not a unified or context diff, so it doesn't apply to any of the Python source code files. The contributed advanced.py seems to have no relationship with any of the functionality included in Python. So I'm rejecting the patch as invalid.
