Recent releases of libxml2 do not provide error context reports for errors detected at the very end of the input string. This appears to be a bug, or at least an infelicity, introduced by the fix for libxml2's CVE-2015-7499. We can hope that this behavioral change will get undone before too long; but the security patch is likely to spread a lot faster/further than any follow-on cleanup, which means this behavior is likely to be present in the wild for some time to come. As a stopgap, add a variant regression test expected-file that matches what you get with a libxml2 that acts this way.REL9_1_STABLE
