As a quick reminder, PEP 409 allows this:

     try:
         ...
     except AnError:
         raise SomeOtherError from None

so that if the exception is not caught, we get the traditional single
exception traceback, instead of the new:

     During handling of the above exception, another exception occurred


My question:

How do we go about putting this in the stdlib?  Is this one of the
occasions where we don't do it unless we're modifying a module already
for some other reason?

Usually I use "from None" in a new code when it hides irrelevant details. But in case of b32decode() (changeset 1b5ef05d6ced) I didn't do it. It's my fault, I'll fix it in next commit.
