I am working on implementing MLton.Exn.history, and in doing so, tickled another
contifier bug, where the contifier produces a program in which a continuation is
called before its definition (yeah, yeah, SSA will be there RSN).

Anyways, the bug is on fft.sml, in the contify2 pass.  The sources which show
the bug are at
	http://www.star-lab.com/sweeks/src.tgz
Matthew, can you take a look?

The shrinker call that the contifier generates is below.
