  - 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.
