I think C mode needs to know a lot more about the syntax of C.  In lisp mode,
I can have text like

	(blat foop (aref (aref (aref gazorch x) y) z))

place the cursor after "foop", type M-C-t, and have

	(blat (aref (aref (aref gazorch x) y) z) foop)

In C mode, I should be able to do the same with

	blat (foop, gazorch->x->y->z);

but instead of 

	blat (gazorch->x->y->z, foop);
I get
	blat (gazorch, foop->x->y->z);

This is easy in lisp because a lisp "expression" is simple to parse: it's
just parentheses.  For C mode, you have to know a lot more about the syntax,
since the syntax is (well, I was going to be nice but...) so stupid.  

I realize this is pretty hard to do, but it's the Right Thing.
