describe-variable overwrites its own input when showing the value of a
buffer local variable that has a default value with long output. To
show this start from "emacs -Q" and in *scratch* write

  (set (make-local-variable 'auto-mode-alist) nil)

and eval it. Then show the value of auto-mode-alist in *scratch* with
describe-variable.

I did that, but I don't see the problem. Can you describe (or show)
what the problem is that you see? What do you mean by "overwrites
its own input"?

Thanks Drew, your are right. It is there. I just did not see it.

So this is not a bug. Sorry for the trouble.
