[issue27261] io.BytesIO.truncate does not work as advertised

[Xiang Zhang]

Xiang Zhang added the comment:

Is this a bug or a documentation matter? Inspecting BytesIO.truncate's code, it does resizing similar to list, this seems to be a designed feature, which conflicts with the documented behaviour.
