I noticed some recent changes to pax that I don't understand.  If someone out
   there knows what
   	flg |= CAF;
   is intended to do, I'd love to know more about it.  :)

it's useless/harmless.  'CAF' means: 'C' - extension flag; 'A' - -A flag;
'F' - flag.  i think.  it's just an internal pax thing.  i think.  :-)
