If we are going to add this feature as a C primitive, it should
ideally free the Lisp programmers from jumping through any additional
hoops, IMO.  So the above should be done in C instead, before
returning the value.  If some applications may want the minibuffer
window and others won't, we should make the function accept an
optional argument to select between these two alternatives.
