Subject: nntpd generate wrong headers

Hi.

nntpd generate wrong "Newsgoups:" header when message cross-posted to
multiple groups. Currently, it write multiple groups separated with
space, but rfc1036 chapter 2.1.3 says "... Multiple newsgroups may be
specified, separated by a comma. ...".
and Path: header too - rfc1036 chapter 2.1.6 says " ... The names may
be separated by any punctuation character or characters (except "."
which is considered part of the hostname). ..."
Currently both headers separated as email-style with spaces,
