complies to present-day (..., present-time! Moah-ha-ha! :-)
elisp-client coding standards. Also generally faster now.
(lyskom-list-news): New function.
(lyskom-iter-list-news): [New] support function to kom-list-news.
* english-strings.el (lyskom-message): Fixed what looked like a
bug in total-unreads.

the strings shown-unreads and no-unreads-shown.
