[remote] Where is S AA p PID currently specified?

[Pedro Alves <pedro@codesourcery.com>]

Hi,

I see this in remote.c:remote_wait, while handling the 'S' and 'T'
stop reply packets:

      switch (buf[0])
       {
        ...

        case 'T':
          ...

	  /* fall through */
	case 'S':		/* Old style status, just signal only.  */
	  if (solibs_changed)
	    status->kind = TARGET_WAITKIND_LOADED;
	  else
	    {
	      status->kind = TARGET_WAITKIND_STOPPED;
	      status->value.sig = (enum target_signal)
		(((fromhex (buf[1])) << 4) + (fromhex (buf[2])));
	    }

	  if (buf[3] == 'p')
	    {
	      thread_num = strtol ((const char *) &buf[4], NULL, 16);
	      record_currthread (thread_num);
	    }
	  goto got_status;


Where's that 'p' after S AA specified?  I don't see it in the docs,
in either S or T stop reply packets description.  Looking through the
file history, it seemed this had to do with some old Cisco
extensions that have since been removed, but this bit got left behind.

Can we remove it ?
