address parsing problem in latest CVS

[Dave Goldberg <david.goldberg6@verizon.net>]

I'm back from a couple week's vacation and at work did a CVS update
before getting into email with Gnus.  I've found that the patches from
9/1 with the following ChangeLog entry have resulted in broken
addresses being passed to smtpmail:

2006-09-01  Katsumi Yamaoka  <yamaoka@jpl.org>

        * gnus-art.el (gnus-decode-address-function): New variable.
        (article-decode-encoded-words): Use it to decode headers which are
        assumed to contain addresses.
        (gnus-mime-delete-part): Remove useless `or'.

        * gnus-sum.el (gnus-decode-encoded-address-function): New variable.
        (gnus-summary-from-or-to-or-newsgroups): Use it to decode To header.
        (gnus-nov-parse-line): Use it to decode From header.
        (gnus-get-newsgroup-headers): Ditto.
        (gnus-summary-enter-digest-group): Use it to decode `to-address'.

        * mail-parse.el (mail-decode-encoded-address-region): New alias.
        (mail-decode-encoded-address-string): New alias.

        * rfc2047.el (rfc2047-quote-special-characters-in-quoted-strings):
        New function.
        (rfc2047-encode-message-header, rfc2047-encode-region): Use it.
        (rfc2047-strip-backslashes-in-quoted-strings): New fnction.
        (rfc2047-decode-region): Use it; add optional argument `address-mime'.
        (rfc2047-decode-string): Ditto.
        (rfc2047-decode-address-region): New function.
        (rfc2047-decode-address-string): New function.

The symptom looks like this (addresses sanitized):

The address in question is always the first on the CC line.  Most of
my addresses are of the form "Real Name" <user@whatever.com>.
Manually stripping the addresses is a workaround but became too
frustrating so I simply backed out to the immediately previous
versions of rfc2047.el, gnus-sum.el, gnus-art.el and mail-parse.el for
now.  Because I'm just back I did not have time to investigate any
further than that but am willing to do so after I get caught up a bit
at work.   I am more than happy to test patches too :-)

Thanks,
