+ [Backport #16949]
+
+	[ruby/psych] Fixing compatibility with libyaml 0.2.5
+
+	The main issue is that commas aren't allowed in local tags.  libyaml
+	was updated to follow the spec, and our tests were out of date.
+
+	See: https://github.com/yaml/libyaml/issues/196

+	https://github.com/ruby/psych/commit/3f5e520fd3
