   --  this procedure is intended to correct the Sloc field in
   --  the first line from a line list covering a given Span.
   --  This means, that all the fields of the Line to be corrected
   --  have been already set as pointing to the beginning of
   --  a given line. Together with setting the Sloc field, this
   --  procedure adjust the Rel_Sloc field.

   procedure Set_Lines (LList : in out Line_List; El : Element);
   --  This procedure creates LList as a list of lines
   --  accessable through El. It gets LList as a list
   --  of Nil_Lines and makes the proper settings for
   --  the components of each line, making them non-nil
   --  It takes all the characteristics of these lines from El,
   --  that is, from the tree on which El is based. This is
   --  "tree-swapping-safe" procedure.
   --  The only call to this procedure is in the third
   --  Asis.Text.Lines function, which explicitly specifies
   --  the bounds of the Line_List to be returned (that is, LList).
   --  The caller makes all the checks needed to make sure, that
   --  the compilation enclosing El really contains lines with numbers
   --  LList'First and LList'Last
