Re: dns.el keywords comm

[Kevin Ryde <user42@zip.com.au>]

Ah, and yet more keywords I had kicking around from a grep of files
without known keywords

	* arc-mode.el: Add "Keywords: files", so the details in its
	commentary can be reached from finder-by-keyword.
	* textmodes/dns-mode.el: Add "Keywords: comm".  It's only an
	editing mode, but it's comms related and sgml-mode.el has "comm"
	on that basis too.
	* textmodes/bibtex-style.el: Add "Keywords: tex".
	* international/isearch-x.el, international/ja-dic-cnv.el,
	international/ja-dic-utl.el, international/kkc.el:
	Add "Keywords: i18n", so they can be reached from finder-by-keyword.

I wondered if ja-dic-cnv.el was slightly internal, but if it's not
advertised somewhere then nobody will know it exists. :-)
