Is this really worthwhile?  It might solve some problems with commands
invoked from the recursive edit, but it doesn't solve all of them,
because the value of history-add-new-input is still set in that
minibuffer.  And it introduces tricky effects due to the variable
being buffer-local for any code that let-binds history-add-new-input,
and could potentially break something because of that.

I'm afraid I don't like this change, for those reasons.
