+A singleton flag passed as a command line option will override the same flag

+A flag that can be passed multiple times will be treated as if its

+```bash
+NODE_OPTIONS='--require "./a.js"' node --require "./b.js"
+# is equivalent to:
+node --require "./a.js" --require "./b.js"
 ```
 
 Node.js options that are allowed are:
