Thanks for the fixes Keith, (and just as quick as usual).

Looks like the message for unhandled exceptions is still reversed:

	$ cat broken_exceptions.5c
	exception foo (real a, real b);

	raise foo (1, 2);

	$ nickle broken_exceptions.5c 
	Unhandled exception "foo" at broken_exceptions.5c:3
	        2
	        1
