Because I believe this is more convenient. It is common practice to
change the behavior of a command by a prefix, and this is what "C-x &"
is good for. It *is* a prefix; just the implementation varies.

Agreed. Now, we have two special cases. I agree also with you to make
this technique more general, but since I'm in the muddy waters of
threads, I'd like to postpone it a bit (or somebody else does). If we
have the more general approach, it deserves documentation.

Best regards, Michael.
