Okay, this is a simple oversight in ruleutils.c: the rule dumper doesn't
have logic to handle whole-tuple function arguments, such as (foo) in
the above example. Will fix.

The ruleutils.c bug cannot explain this however, since ruleutils won't
even be invoked. Can you find a sequence to reproduce it?
