The following patch should do that.  It also uses `add-to-history'
to add the current search string to `query-replace-from-history-variable'
to improve code in the same function.  This requires adding a new
argument KEEP-ALL to `add-to-history'. Its meaning is the same as the
argument KEEP-ALL of `read-from-minibuffer'.
