Try this and let us know how you get on...  $LASTWIDGET test is
unsophisticated but probably covers the most obvious cases.


_complete_failed() {
  # Only complete if first attempt at completion failed.
  # Usage:
  #   zstyle ':completion:*' completer _complete _complete-failed
  #   zstyle ':completion:complete-failed:*' completer <your-completers>

  if [[ $LASTWIDGET = *complete* && -z $_complete_failed_active ]]; then
    local _complete_failed_active=1
    local -a completers
    local curcontext="complete-failed:::"
    _main_complete "${completers[@]}"
  fi
}
zstyle ':completion:*' completer _complete _complete-failed
zstyle ':completion:complete-failed:*' completer _files
