    It does, if passed a dead buffer.  Maybe we should change that.

That surprised me, but I guess it is true.  Maybe it should not be
changed.

Meanwhile, `get-buffer' will not find a dead buffer by name.
So I don't see a need to create a `get-live-buffer' function.
Unless the purpose were only to get an error if the argument
is a dead buffer.
