Yes, I guessed that they were the same as `C-x 8'.

1. I think that in both cases we need to identify them somehow as key remappings
in the output.

2. What is the new feature that causes the `A-' bindings to now show up in
addition to the `C-x 8' bindings?  Shouldn't that feature be called out in NEWS,
even if it is just a new set of key remappings?  What was the rationale behind
the change?
