Agreed.

"matching" -- no way!  "associating" -- of course.

Agreed.

However, from *NONE* of these three points can the claim I have underlined
be deduced.  The statement (which I accept, of course!) that vertical
alignment is an effective way of associating things tells us that the
statements, not being at the same syntactic or conceptual level as the
brackets, would benefit from being indented.  Hence the old Algol 60
convention:
	if <condition> then
	   begin
	      <decls>;
	      <stmts>
	   end
	else
	   begin
	      <decls>;
	      <stmts>
	   end

Let me make my request clearer.  Can anyone cite a study which shows
	if (...)
	    {
	    <stmt>
	    <stmt>
	    }
to be superior to
	if (...)
	  {
	    <stmt>
	    <stmt>
	  }
