Rather a 'bug-fix' release. Intended to add additional symbols to group names. I'd like to add support for explicit fetching some headers only and giving the message a more MIME-like behaviour but I'm afraid there is nowhere written how XHDR/HDR would behave with multiline headers nor I found a suitable package (mime[1] seems to not include even parsing the headers only and mime-string[2] does not take into account comments which may or may not be a problem with Message-ID comparaison).
