Change prompt history yet again.  Now the history is copied before
use, and the user's editing changes are remembered for each element in
the history.  When the user exits the minibuffer, all of the changes
are discarded.

Also: eliminate HISTORY-DEFAULT option; HISTORY-INDEX now subsumes
that role.
