I find arguments about defaults a waste of time.  So I think instead
of arguing and polling, we should just make sure there's a completion
style that closely resembles what you want, i.e. candidates are found
by matching their beginning with what the user typed.  Currently, I
find no such style in what minibuffer.el offers, or maybe there's a
bug (see my other mail for bug #9591).

(Btw, why do we have 2 separate bug reports about the same issue?)

I agree.
