Style/RescueModifier redundant correction

[marcandre]

I got this auto-correction:

-        Ext::RegexpNode.parsed_cache[str] ||= (Regexp::Parser.parse(str) rescue nil)
+        Ext::RegexpNode.parsed_cache[str] ||= begin
+                                                begin
+                                                 Regexp::Parser.parse(str)
+                                                rescue StandardError
+                                                  nil
+                                               end
+                                              end

There's a redundant begin-end pair...
