!  Next the WriteListFrom routine, a flexible object-lister taking care of
!  plurals, inventory information, various formats and so on.  This is used
!  by everything in the library which ever wants to list anything.
!
!  If there were no objects to list, it prints nothing and returns false;
!  otherwise it returns true.
!
!  o is the object, and style is a bitmap, whose bits are given by:
