Comment 14 for bug 386069

Ok, let's try another one for Win32 with rev. 21571.
Tested with Ubuntu 9.04 and Vista SP1, and it looks good (SVG files created with 0.46 and dev, relative and absolute path tested).

I didn't find how to fix with os.path or urlparse and therefore I had to check the OS version and remove the unnecessary part of the string (the first 3 chars: '/C:') when the path is absolute.
Please tell me (or patch) if you have a cleaner fix.
