Currently demo calls source with a hard coded max.deparse.length = 250
so you can't really see the demo properly in some cases. Note the
[TRUNCATED] below. (1) It would be nice if demo passed max.deparse.length
(and other args to source). (2) Also a larger max.deparse.length default would
be nice to make it less likely one would have to set it in the first place.
