It seems that fucntions utf-7-decode and utf-7-encode are
designed to be called only as pre-write/post-read functions
of a coding system utf-7 (and commented out coding system
utf-7-imap) in lisp/international/utf-7.el.

I think the right thing is to uncomment all codes for
utf-7-map in utf-7.el, and modify gnus to use normal
encode/decode-coding-region/string with utf-7-imap.

I've just committed the former change.  Could someone do the
latter change?
