gnus: incorrect conversion of Subject and From field from utf-8 to koi8-r

[Boris B. Samorodov]

Symptoms:


I do have a letter with the next Subject:
-----
Subject: 
=?UTF-8?B?W2lwdC5ydSAjMTYzXSDQkNCy0YLQvtCe0YLQstC10YI6INCc0KHQmjog0KHQ?= 
=?UTF-8?B?nyDRgtC10YHRgg==?=
-----

In command-line mode I can do...

$ echo 
"W2lwdC5ydSAjMTYzXSDQkNCy0YLQvtCe0YLQstC10YI6INCc0KHQmjog0KHQnyDRgtC10YHRgg==" 
| base64 -d | iconv -f utf-8

...and receive the answer:

[ipt.ru #163] АвтоОтвет: МСК: СП тест

But gnus (from cvs as emacs) shows the next line...

Subject: [ipt.ru #163] АвтоОтвет: МСК: СП тест

...which is wrong.

The bug appeared to be at illegal concatenation of
=?UTF-8?<foo> =?UTF-8?<bar> parts of the Subject.

The same bug is at From field (and maybe somewhere else).
