Sorry, I meant the announcement of the variable's presence in NEWS, with no
further explanation.  If it is announced without explanation then its doc should
be available.  But it is preferable to just mention in NEWS that it is only for
X Window.

That would be sufficient to dispel any confusion, IMO.

(That says better what I was trying to say above.)

Thx.  If it will, then you can close this bug if you think that's appropriate.
It seems that some, at least, feel that bug reports about NEWS problems are
uncalled-for before the actual release.
