adds illegal semicolon when a function is assigned to a variable in the middle of statements

[GoogleCodeExporter]

What steps will reproduce the problem?
1. write javascript code like
for exameple, if you `fixjsstyle` some code such as
```javascript
var a = 1,
    b = 3,
    c = {},
    d = function() {},
    e = "asdf";

the result will look like this.
var a = function() {},
b = "asdf";
2. run fixjsstyle

expected result:
var a = function() {},
b = 'asdf';

but I get
var a = function() {};,
b = 'asdf';

due to that semicolon before comma(,) the result is wrong.
