Summary: Mangled "Re:" in i18n subject header

Initial Comment: Hello!

Look, here is the subject from a mailman-managed mailing list:

Subject: [Bug] =?koi8-r?B?UmU6IFtCdWddIFJlWzJdOiBbQnVnXSBSZTogW0J1Z10gUmU6IFtCdQ==?= =?koi8-r?B?Z10g8NLPxMHF1NPRINPMwdfRztPLycog28vBxg==?=

Let me decode it:

import sys, email.Header print email.Header.decode_header(sys.stdin.read())

[('Subject: [Bug]', None), ('Re: [Bug] Re[2]: [Bug] Re: [Bug] Re: [Bug] \xf0\xd2\xcf\xc4\xc1\xc5\xd4\xd3\xd1 \xd3\xcc\xc1\xd7\xd1\xce\xd3\xcb\xc9\xca \xdb\xcb\xc1\xc6', 'koi8-r')]

Look how many "Re:"s re there!

The problem arise when Mailman adds list tag (in this case [Bug]) to an *encoded* header. Mailman must decode the header and check for "Re:" and list tag in the decoded header.

All mailing lists that I know are guilty with the bug. Let Mailman be the first that fixes it! Thank you.

Oleg, have you tried this with MM2.1? I think there's code in there that tries to decode the header first before searching for the prefix. I'm not surprised MM2.0 doesn't do the right thing, but MM2.1 should.
