Changes to news:* handleing

Our local news guru (Bob Sloan) pointed out to me that the Web use
of "LIST" to retrieve all the articles on the system was rather ugly
and that what we should be using is "LIST NEWSGROUPS". "LIST"
returns the name of each group plus the last article number and
the first article number and then a moderated code. "LIST" looks like:

NEWSGROUPS

* alt.3d 5025 4760 y
* alt.abortion.inequity 12827 12537 y
* alt.abuse-recovery 2 3 m
* alt.activism 60722 60194 y

Pretty darn ugly. "LIST NEWSGROUPS" returns the name of each
newsgroup and a description. With some slight code changes
we now get:

NEWSGROUPS

alt.3d
Three-dimensional imaging.
alt.abortion.inequity
Paternal obligations of failing to abort unwanted child.
alt.abuse-recovery
Companion to alt.sexual.abuse.recovery. (Moderated)
alt.activism
Activities for activists.

I have attached code diffs for both the Lynx version of
the WWW library changes and the XMosaic 2.2 version, since
there are differneces in the file. I will have these changes
in Lynx version 2.2

Does anyone know of any server that doesn't support "LIST NEWSGROUPS"
I tried INN, ANU News and a CNEWS installation and they all worked.
