- ci_test_noexceptions: the element access tests compare the exceptions of json_view and basic_json through exception_of(), which catches them outside a CHECK_THROWS; with JSON_NOEXCEPTION the first one aborted the test. Compile those comparisons only with exceptions. - clang 3.6: value-initialize a const json_view, as in the tests of json-view/10-view-document. - Format three new documentation examples with the pinned astyle, which the "check" job runs once it gets past the amalgamation step.
