Sure, but that's about as long as the other workaround, especially considering
following it with `C-x n w'.

I don't mind using a workaround if there's a good reason why `C-M-x' does what
it does and it shouldn't be changed.

No, but I suppose it too could be asked.

My question is whether we really want `C-M-x' to do what it does instead of just
pick up the innermost def* containing point.

And why it does the former.  If there's a good reason, I'd like to know it.
