  13 /* This iod stuff is a silly little package to emulate the old qi_in stuff,
  14  * which emulated the stdio stuff.  There is a big assumption here, that the
  15  * rx_Read will never be called directly, by a routine like readFile, when
  16  * there is an old character that was pushed back with iod_ungetc.  This
  17  * is really bletchy, and is here for compatibility only.  Eventually,
  18  * we should define a volume format that doesn't require the pushing back
  19  * of characters (i.e. characters should not double both as an end marker
  20  * and a begin marker)
