Here's another one. I hadn't realized that it was useless to target the 2.x codebase. So I re-worked this on py3k. The change is non-trivial, since the non-windows/non-os2 part of the code has significantly changed in 3k. This time, since "oname" is released later and used in error conditions, I thought it was worth it to allocate a new PyBytes for the default value.

I also modified the documentation so that it tells about path's default value.
