Again, what's the use case? Why do you want the default to be singled

out in some way?

I'm curious too. I don't say it couldn't be useful,

but I wonder what the aim is.

Wouldn't one normally associate a default with some sensible setting worth looking

into most times?  Perhaps this could be a user setting. 

BTW, note that the default value (or even any of a

list of default values) provided need not be among

the candidates for completion, if completion is lax

(REQUIRE-MATCH = nil). E.g.:

(completing-read "q: " '("a" "b" "c" "d")

nil nil nil nil "e")
