Yes, being able to move from `execute-extended-command-for-buffer' to
`execute-extended-command' makes sense, but I'm not sure the other
direction is as useful.  And while there's only two of these commands
today, I think it's likely that (in the future) that we'll grow more of
these.

I'm not quite sure how to implement this, though -- we basically end up
in `completing-read', and `execute-extended-command-for-buffer' would
have to define an `M-x' binding there, I guess...  and then somehow call
`read-extended-command' with the text already in the minibuffer.

Anybody got an idea as to how to implement this without rewriting
`read-extended-command' completely?
