Support comma-first style for variable declaration

[vincentbernat]

Hey!

The comma-first style for variable declaration looks like that:

var a= 47
  , b = 48
  , c = 49
  ;

This is a somewhat popular choice because it is easier to spot a missing comma and adding a variable at the end doesn't produce a two-line patches.

Currently, web-mode does that:

var a = 47
, b = 48
, c = 49
;

Funny enough, if I replace one value by a function call, I get this:

var a = require('titi')
    , b = 48
, c = 49
;

Would it be possible to support this comma-first style?

Humm, I just noticed that the more classic style is not supported correctly either:

var a = 47,
    b = 48,
    c = 49;

Instead:

var a = 47,
b = 48,
c = 49;

@vincentbernat please test the last commit

That was fast!

var a= 47
  , b = 48
  , c = 49
;

Usually, the semi-colon is aligned with the comma, but I can live with that. However, it seems that when there is a function call, things go awry:

var a = require('titi')
              , b = 48
              , c = 49
;
