"General text sorting routine to divide buffer into records and sort them.
We consider this portion of the buffer to be divided into disjoint pieces
We divide the accessible portion of the buffer into disjoint pieces
called sort records. A portion of each sort record (perhaps all of it)
is designated as the sort key. The records are rearranged in the buffer
in order by their sort keys. The records may or may not be contiguous.
