I'm not familiar with wl/elmo code nowadays, but AFAICT, wl/elmo
doesn't seem to have the one like nov that keeps date information.
So, I've made changes in sb-rss.el and sb-rss-blogs.el in the way
I wrote last.  sb-atom.el is unchanged.

Maybe the argument name `quit-immediately' has to be more clarified.
