Ahem, I'm thinking too much about styles already. Of course there is a 
way:

  zstyle ':completion:*:*:-command-:*' tag-order 'maybe()' -

  maybe() { [[ -n $PREFIX ]] && comptry "$@" }

or somthing like this:

  maybe() {
    if [[ -n "$PREFIX$SUFFIX" || $1 = messages ]]; then
      comptry "$@"
    else
      _message 'not with an empty word...'
    fi
  }

Good enough?
