It can't delete duplicates if the history contains several of them.
This is possible when the value of `history-delete-duplicates' is
changed during the Emacs session.  But when it is set in .emacs, your
patch will guarantee that no duplicates are added to the history.  So
for the case when the value `history-delete-duplicates' isn't changed
during the Emacs session, your patch is ok.
