Sorry, for this part I was thinking of incremental completion, as in Icicles.
With vanilla Emacs completion, this would be under user control via TAB: wait
until s?he hits TAB to perform the test.

My remarks about min chars and a delay are pertinent for vanilla Emacs only in
the context of incremental matching, such as in incremental search. They don't
apply to completion.
