The problem with this proposal is that any command in-between will
break the chain.  One must remember not event to move point.  That
could well be problematic: for example, imagine that I'm not sure
whether I want the current candidate, and to be sure I need to scroll
the window a bit, because what M-. displayed doesn't show enough
(e.g., because the window is too small).
