[issue18022] Inconsistency between quopri.decodestring() and email.quoprimime.decode()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

There are other inconsistencies. email.quoprimime.decode(), binascii.a2b_qp() and pure Python (by default binascii used) quopri.decodestring() returns different results for following data:

           quoprimime  binascii  quopri

 b'='      ''          b''       b'='
 b'=='     '='         b'='      b'=='
 b'= '     ''          b'= '     b'= '
 b'= \n'   ''          b'= \n'   b''
 b'=\r'    ''          b''       b'=\r'
 b'==41'   '=A'        b'=41'    b'=A'
