 accordingly

hardcoding a base seq from 0 to 9 was the culprit behind Ticket #7769

Subject: [PATCH 3/4] Adding test cases for a scenario of increased arity limit

Test cases are based on calling apply to forward to the and_ predicate
an increasing number, from 2 to 15, of true_ constants. Since the arity
limit on the current version is set to 5,
BOOST_MPL_LIMIT_METAFUNCTION_ARITY and
BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS must be appropriately set.
