JavaScript indentation for var blocks using built-in javascript-mode

Question

I get the following:

   var 
   a = 5,
   b = 6, 
   c = foo();
   /* code continues */

I want:

   var 
       a = 5,
       b = 6,
       c = foo();
   /* OUTDENT, code continues */

I know as per How to get js-mode to properly indent continued (compound?) var declarations? there is some hack for js2-mode which gets it done. I would like to know how to do it with javascript-mode (the built-in one, into emacs 24). "var" should indent one level until the first semicolon after var. Comma-first-style should not alter that.

Ideally, I could have it in my init.el, which I could then sync to every computer I am working on. Is that possible? How do I do it?

Put a = 5 on the same line as var. Otherwise, there's no mode that supports this.
Use Emacs trunk. The bit of indentation code from js2-mode that does this has been committed to js-mode just recently, and it was too late for 24.3. Alternatively, just use a recently released Emacs, and copy js.el from the Emacs source tree to a directory in your load-path.

I have compiled emacs trunk, and it works (--version says 24.3.50.1). Thanks.
