Awesome, thank you Peter! Now it works. I extended my function in the
following way:

  function _term_list(){
    local -a w

    for SESSION in $(pidof  zsh); do
      PA=$(readlink -n /proc/${SESSION}/cwd)
      w+=(${(D)PA})
    done

    compadd -aQ w
  }

And btw, also spaces are recognized correctly and are terminated with a
backslash in front of it, when inserted on the commandline.

Cheers,
Jester
