Re: Strange change in backquote expansion

[Richard Stallman]

      ``(,,@(list (list arg))))

I don't think that is a meaningful expression.  ,@ is supposed to be
used inside of a list, to cause appending into that list.  Using it
after a comma means it isn't in any visible list.

I've tried to figure out what the first backquote ought to expand
into, and I can't.
