    - Issue #6939: Fix file I/O objects in the `io` module to keep the original
      file position when calling `truncate()`.  It would previously change the
      file position to the given argument, which goes against the tradition of
      ftruncate() and other truncation APIs.  Patch by Pascal Chambon.
