[news.misc] Are duplicate headers allowed?

As some of you may know, I am reading mail on an IBM clone, using the
UFGATE software.  Because of the way news is spooled, there is no
way to add on headers not directly supported by my news software
(such as References:, or Summary:).  In order to support these,
I am using a kludge program (written by Jeff Sheese) that allows
you to add headers by placing a ^B (ASCII 0x02) before the first
header, and a blank line after the extra headers.  This works well,
and I can now feel good about supporting the References: header.

Unfortunately, it isn't very smart.  All it does is delete the \n\002
before the headers, without checking to see if one of the headers
you're trying to add is already there.  Because my news software
automatically adds required lines such as Newsgroups: and From:,
I have no way of changing them.  Would it hurt anything to have
a duplicate Newsgroups line, with more newsgroups added?  For example,
my news software only allows you to post to one group at a time (no
cross-posting).  If I (for some strange reason), want to post to
both soc.women and talk.abortion, would a message like this be legal?

(What I'm really asking is, "Which Newsgroups: header would be used?"
Would it be the last one encountered (soc.women,talk.abortion), the
first one encountered (soc.women), or neither?)  RFC-1036 doesn't
say anything about this...
