+Subject: [PATCH] Always issue deprecation warning when calling Regexp.new with
+ 3rd positional argument
+Reference: https://github.com/ruby/racc/commit/9b0a22c999c3c55ec2aca585468d456d1eca2378
+
+Previously, only certain values of the 3rd argument triggered a
+deprecation warning.
+
+First step for fix for bug #18797.  Support for the 3rd argument
+will be removed after the release of Ruby 3.2.
+
+Fix minor fallout discovered by the tests.
