There is another bug in your version of smart-insert-last-word: repeated
calls to it don't go back in the history. Rather than doing the word
splitting yourself, you should always call insert-last-word -- with an
argument of 2 or greater, when necessary.

The solution might be a synthesis of my first version and yours -- a widget
that is smarter than mine when determining the last word, but nevertheless
calls insert-last-word, so that the shell can go back the history on
subsequent calls.
