 Tor marks a managed proxy as broken when it receives unknown output from
 it.

 This is bad for forward compatibility. The 180 spec also wants managed
 proxies to ignore unknown output:
 {{{
   Tor MUST ignore lines with keywords that it doesn't recognize.
 }}}

 In `src/or/transports.c`:
 {{{
   log_warn(LD_CONFIG, "Unknown line received by managed proxy. (%s)",
 line);

  err:
   mp->conf_state = PT_PROTO_BROKEN;
   log_warn(LD_CONFIG, "Managed proxy at '%s' failed the configuration
 protocol"
            " and will be destroyed.", mp->argv[0]);
 }
 }}}
