Subject: Fixed sorting. needs_sorting was getting set to 0 when sorted
 happens, but

2001-01-06  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-sorter.c, e-table-sorter.h (ets_sort): Fixed sorting.
	needs_sorting was getting set to 0 when sorted happens, but
	needs_sorting tells you whether or not the sorter is sorted or
	not, not whether the sorting has happened.  Documented the
	needs_sorting variable.
