Please use clang-format. Some of the indentation in this patch is a
little unusual. Also, in a couple of the tests you've added "FIXME: This
test should fail." without any further explanation. Please be a little
more specific in these comments (ie, "yaml-bench should exit with an
error", or "the output should be xyz"), or write the test to pass for
the correct output and leave the XFAIL in place (then they'll XPASS when
the bug is fixed).
