So now there is:
Now CE_EXTENDED_FLAGS & 0x803FFFFF is bad because:
* CE_EXTENDED_FLAGS & 0x0000FFFF are saved flags (not extended)
* CE_EXTENDED_FLAGS & 0x003F0000 are in-memory flags
* CE_EXTENDED_FLAGS & 0x80000000 is 'extra flags' bit
(this is not mentioned in quoted comment; I'm not sure if
it needs to be or not)
Is that correct?
