New submission from Michael Harris <pw.michael.har...@gmail.com>:
When given an invalid base64 string that starts with a valid base64 substring,
the functions will return the decoded bytes only up to the substring rather
then ignoring the non-alphabet character.
Examples:
>>> base64.b64decode("AAAAAAAA")
b'\x00\x00\x00\x00\x00\x00'
>>> base64.b64decode("AA=AAAAAA")
b'\x00\x00\x00\x00\x00\x00'
>>> base64.b64decode("AAA=AAAAA")
b'\x00\x00'
