     "BUG" indicates a situation that should never occur if the program is
correctly coded; for example, something like the following:

	if (i < 0 || i > 3)
	    return -1;
	switch (i) {
	    case 0: /* ... */ break;
	    case 1: /* ... */ break;
	    case 2: /* ... */ break;
	    default: log("BUG: impossible value for i (%d)", i); return -1;
	}

In this case, it indicates that a PART message was received for a user who
was not recorded as being on the channel they were supposedly parting,
which means there's a bug in either Services or the ircds.  (Most probably
this is a Services bug, but since it could potentially be caused by bad
messages from the uplink server this probably shouldn't be marked "BUG" as
the other BUG cases are.)
