New description:

 The function parse_socks and its interactions with the functions that call
 it have grown nigh-unmaintainably complex.  Let's replace it with a
 simple, more linear function.  Key points:

   * State should be kept explicitly.  Let's forget this "if the socks
 version is set, we've parsed this much, ..." business.
   * The function should dispatch first on state, next on anything else.
   * We should think of a much better interface; the functions that call
 parse_socks have grown way too tricky.
