Sorry for being very slow here. I was busy and only skim read the
thread before.

If we just want a shell widget, I've been using this for years:

copy-last-word() {
  setopt localoptions noksharrays
  local words
  words=( "${=LBUFFER}" )
  if [[ $LASTWIDGET = copy-last-word ]] && (( clwcount > -$#words )); then
    (( clwcount-- ))
  else
    (( clwcount=-2 ))
  fi
  LBUFFER="${LBUFFER%$words[-1]}$words[clwcount]"
}

It doesn't duplicate the current word at the first invocation like
copy-prev-word does - I find that useless. I suspect that Peter's
patch does a better job of using WORDCHARS or whatever. This just
worked for me. I'm sure it could be better.

What I've been meaning to do in ages is combine this with 
insert-last-word so you can use insert-last-word to go up a few
lines and then go back along the words of that previous line.
