[issue39840] FileNotFoundError et al show b-prefix on filepaths if passed as bytes

[Augie Fackler]

New submission from Augie Fackler <lists at durin42.com>:

I'm not really sure if this is a bug per se, so please feel encouraged to close as WAI if you like, but:

>>> open(b'foo', 'rb')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
FileNotFoundError: [Errno 2] No such file or directory: b'foo'

Seems a little weird to me (and it shows up in the UI layer of hg), because the path-as-bytes seems like it shouldn't show up in the human-readable version of the exception (I think I would have expected the fsdecode() of the bytes, for consistency?)

But that's up to you. If the presentation format of this feels right to Python that's no big deal.
