+Subject: test: Escape curly braces in regex
+
+Curly braces in perl regex are supposed to be escaped, recent
+versions of perl complain when they aren't:
+
+Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/%{ <-- HERE (\w+)}/ at ./run line 114.
+Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/%{ <-- HERE \?}/ at ./run line 290.
