Yes, and I want to add that if the user types RET with empty input,
then it should put onto the history list not the whole list of default
values, but only the first element of such list, i.e. the same element
that minibuffer-reading functions return.

BTW, currently there is an inconsistency in the `read-from-minibuffer'
function.  Typing RET with empty input after evaluation of:

(read-from-minibuffer "prompt: " nil nil nil nil "default")

adds the string "default" to the history list, even though this function
returns an empty string.  I don't know whether this should be fixed or
maybe it causes no problems.
