Re: Documentation not clear for the Lisp function set-variable

[Richard M. Stallman]

    Maybe set-variable should first try to complete non-obsolete aliases,
    and filter out obsolete aliases (but still accept them).

I don't like that idea.  The command should accept *all* names,
whether obsolete or not.  But it would be nice to inform the user in
the echo area that the name is obsolete, and give the new name if any.
