… arguments (pythonGH-153423) IMAP4.select() and IMAP4.uid() formatted the mailbox and command argument with %s in their error messages, which raised BytesWarning under -bb when the argument was bytes and masked the real error. Use %r instead, which is safe for bytes and also quotes the value.

IMAP4.select() and IMAP4.uid() formatted the mailbox and command argument
with %s in their error messages, which raised BytesWarning under -bb when the
argument was bytes and masked the real error. Use %r instead, which is safe
for bytes and also quotes the value.
