bug#8576: 23.2; js-mode doesn't support multi-line variable declarations

[Felix H. Dahlke]

The problem can be reproduced as follows:

1. Open a JavaScript file or load js-mode
2. Insert the following code:
   var i = 1,
       j = 2;
3. Observe that "j" is not highlighted and that pressing TAB on the
second line doesn't indent it correctly.

Highlighting works correctly if both variables are declared on the
same line:
    var i = 1, j = 2;
