I've applied the patch, but there were bugs.  It referred to an unbound
variable called "hdr", which I've changed to bcc.  Please look over the
resulting code.

Also, I get these warnings:

In end of data:
gnus/mml-sec.el:429:1:Warning: the following functions are not known to be
    defined: mail-strip-quoted-names, message-fetch-field, gnus-subsetp
