[R6RS] What are predicates?

Some of the list procedures we're adding accept predicates as
arguments.  As per R5RS, a predicate is a procedure returning a
boolean value, i.e. #t or #f.  However, procedures like `exists' could
also handle any true value returned by the predicate.  Should they?
(I'm thinking yes.)
